HOW BECOME A TRIGONOMETRY & PRECALCULUS MASTER IS SET UP TO MAKE COMPLICATED MATH EASY:
This 302lesson course includes video and text explanations of everything from Trigonometry and Precalculus, and it includes 89 quizzes (with solutions!) and an additional 10 workbooks with extra practice problems, to help you test your understanding along the way. Become an Trigonometry & Precalculus Master is organized into the following sections:

Angles and their measure, including degrees, DMS, and radians

Angles in circles, including oriented arcs, circular sectors, and linear and angular velocity

The six circular functions, which are sine, cosine, tangent, cosecant, secant, and tangent

The laws of sine and cosine, including Heron's formula

The unit circle, and how to use it to complete a triangle

Graphing the trig functions using period and amplitude, horizontal and vertical shifts, and other transformations

Trig identities like evenodd, sumdifference, doubleangle, halfangle, producttosum, and sumtoproduct

Inverse trig functions and their graphs

AND HERE'S WHAT YOU GET INSIDE OF EVERY SECTION:
Videos: Watch over my shoulder as I solve problems for every single math issue you’ll encounter in class. We start from the beginning... I explain the problem setup and why I set it up that way, the steps I take and why I take them, how to work through the yucky, fuzzy middle parts, and how to simplify the answer when you get it.
Notes: The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.
Quizzes: When you think you’ve got a good grasp on a topic within a course, you can test your knowledge by taking one of the quizzes. If you pass, great! If not, you can review the videos and notes again or ask for help in the Q&A section.
Workbooks: Want even more practice? When you've finished the section, you can review everything you've learned by working through the bonus workbook. The workbooks include tons of extra practice problems, so they're a great way to solidify what you just learned in that section.

Ultimate guide to math word problems Intermediate Part One
Learn to tackle word problems in the easiest way possible!
Created by Chanda Academy  Education provider
Students: 12239, Price: Free
Students: 12239, Price: Free
**May 2016 update: Course completely redesigned with a lot of new questions to further improve your learning**
Welcome to Ultimate guide to maths word problems  Intermediate Part One. This course is tailored towards Grade 9 students who're looking to get a leg up on their ability to tackle the dreaded word problems. If you have significant trouble with problem solving questions, then I suggest you enrol in Ultimate guide to maths word problems  Beginners Part One and Part Two before attempting this course as we'll be building on a lot of the things covered in those two.
This will always be a FREE course. Once you've completed it and would like to test your skills further, then have a go at the Ultimate guide to maths word problems  Intermediate Part Two course.
What are word problems?
We all learn basic concepts like fractions, decimals, algebra etc. at school. We know how to add fractions or simplify algebraic expressions, but what stumps us is having to apply our knowledge to "real life scenarios". These are word problems. I'm sure you've come across these during your schooling. For example, The authors of a book are going to share the royalties in proportion to the number of chapters they have each written. Charlie wrote 4 chapters, Brad wrote 3 and Nigel wrote 5. If they need to share $24,000, how much will they each get? Show full working.
This is a typical ratiobased word problem. Not sure how to do these? Then let me help :)
A lot of students find these types of practical questions quite challenging to answer as they have trouble linking their basic knowledge of ratios in this case to the real life scenario at hand.
How will this course help you?
Every topic that I cover in this course will come up in some form in years to come. I go through every single topic in a step by step form so it's really easy for you to follow along. Not convinced? Then I suggest you check out the previews before you decide to enroll, to make sure my teaching style is easy to follow, I am very confident that it is. To go a step further, Udemy's 30day money back guarantee should also make you feel at ease.
What will this course have?
As I mentioned, this particular course is geared towards students in Grade 9. I will go through a number of problem solving / word problem questions, split into the different topics listed below. I go through each question in a systematical step by step manner making it super easy to follow along and adopt in your own workings.
What topics will the course cover?
The course will cover most topics that come up in these grades and are prone to have a lot of worded problems attached to them.
Indices, algebra, linear equations, geometry, trigonometry, ratios, finance, measurement, probability and quadratic algebra.
**BONUS** I've also added worksheets (with answers) for each topic to help you further test and implement your learning from the lectures.
**WARNING** I'm going to assume knowledge of how to perform the actual operations involved with these word problems. This course is only to show how to approach the word problems, NOT the operations behind them.
My next course will be Ultimate guide to maths word problems  Intermediate Part Two, where I will work through topics and questions, typically covered at the Grade 10 level i.e. one level harder than this course.
Why did I decide to create two intermediate courses?
If you're wondering this then that was because I saw that the level of difficulty jumps up heaps from Grade 9 to Grade 10 and some new concepts are introduced as well. So instead of piling everything into one course and confuse you, I decided to create two different ones so you could gradually go up in levels :).
Something missing in the course?
If you find I haven't covered a topic that you need at this level, let me know on the discussion board and I'll be happy to add it in :)
I can guarantee that you'll be miles ahead of the competition if you take this course seriously and best part about being able to do it all is that you can teach others as well. When you're willing to spend upwards of $50 an hour for a private tutor, it seems like a no brainer to at least give this a go, so that you have access to your very own private tutor any time you wish.
I'm good with messages and emails so if you have questions, make sure to get in touch with me. And furthermore, I want you guys to make full use of the discussion board because one of the best ways to learn is by sharing your knowledge with others. Thanks guys, really hope you enjoy.

This course is going to cover all the concepts that will be covered in school from basic trigonometry topics such as Pythagoras' Theorem through to more advanced topics such as Angles of Elevation and Depression. During my time as a tutor, I've seen students really struggle to grasp the different elements of this topic, so this course can serve as a permanent reference point for you guys going forward.
If you're high school at the moment and have started doing trigonometry, then this course will be a big help because it can either complement your studies at school or serve as the official guide. I will step you through every topic systematically and run through a number of questions to really help you cement your learning.
A lot of my students are actually parents who are home schooling their kids, so if you're someone looking to brush up on your knowledge to help your kids at home, I know this course along with all my other courses will be a big help.
I go through every single topic in a step by step form so it's really easy for you to follow along. Not convinced? Then I suggest you check out the previews before you decide to enroll, to make sure my teaching style is easy to follow, I am very confident that it is. To go a step further, Udemy's 30day money back guarantee should also make you feel at ease.
What topics will the course cover?
I'll cover the following topics in the course:
Pythagoras' Theorem:
 Rightangled triangles
 Finding the hypotenuse
 Finding the other sides
 Composite shapes
 Pythagorean triples
 Pythagoras' Theorem in 3Dimensions
Trigonometry:

Why Trigonometry?
Trigonometry is a huge part of maths at school and it's a shame that a lot of the fundamentals are just not taught properly by teachers and then students are expected to do quite advanced operations in higher grades. That's why I created this course for you guys so you always have a reference point and furthermore always have access to me when you need help :)
**BONUS** I've also added worksheets (with answers) for each chapter to help you further test and implement your learning from the lectures.
I'm working on a number of courses like this, which cover a variety of maths topics. I'll keep you guys updated as I release them :)
Something missing in the course?
If you find I haven't covered a topic that you need at this level, let me know on the discussion board and I'll be happy to add it in :)
I can guarantee that you'll be miles ahead of the competition if you take this course seriously and best part about being able to do it all is that you can teach others as well. When you're willing to spend upwards of $50 an hour for a private tutor, it seems like a no brainer to at least give this a go, so that you have access to your very own private tutor any time you wish.
I'm good with messages and emails so if you have questions, make sure to get in touch with me. And furthermore, I want you guys to make full use of the discussion board because one of the best ways to learn is by sharing your knowledge with others. Thanks guys, really hope you enjoy.

Students: 722, Price: Paid
Learning about analytic trigonometry can be tough. Once you feel you mastered one type of problem you get stumped on the next. This course is structured to not leave you behind in the dust. I start off each section with basic definitions and processes you will need to know moving through the course. I then present two types of videos to you for each skill. First is the overview video where I explain the concept as a whole like a typical lecture in a classroom. I then work through multiple examples showing you step by step how to complete different types of problems. We both know watching someone do math is not the best way to learn. You have to practice! Each section you are provided with multiple worksheets to practice your skills as well as the answer to check your answers. Revert back to videos if you get stuck and forget how to solve the problems. Once you feel you have a good grasp of your understanding it is time to take your quiz. There are multiple quizzes provided for each section. Take the quizzes as many times as you need to earn 100%. There is no pressure you are hear to learn. By taking this course you will not only gain a better understanding of analytic trigonometry but you will gain confidence to solve more problems on your own. That is why I created this course. I want students to no longer fear learning math or walking into their math class because they just don't understand. Everyone can learn math. Some it just takes a little longer, some just need a little boast and some need a course like I designed to guide them through the material. Heck once you complete this course, show your teacher! You deserve and A. I am here for you and by joining this course you are now one of my students just as important to me as the 140 students I teach in the classroom during the school year. So please keep in touch, let me know how I am doing and if there is anything extra I can provide to assist you with your learning of analytic trigonometry.
