HOW BECOME A TRIGONOMETRY MASTER IS SET UP TO MAKE COMPLICATED MATH EASY
This 60-lesson course includes video explanations of everything from Trigonometry and Precalculus. Become a Trigonometry Master is organized into the following sections:
HERE'S WHAT SOME STUDENTS OF BECOME A TRIGONOMETRY MASTER HAVE TOLD ME:
"Krista's courses are the absolute best you can find online, as far as I'm concerned. I feel like I am actually learning something from them!" - Jon K.
“The Instructor has an excellent command of the subject material and a great way of presenting it. In addition to that, she has a very pleasant voice that keeps you attentive.” - Robert S.
“This is an excellent course to become more familiar with trigonometric equations. The step by step instruction is very is to follow. I found it very helpful to follow along with solving the problems on paper to solidify the learning experience.” - David M.
“Krista explains everything in "simplest terms" so even if you haven't worked with this stuff for a while, she makes it totally easy to get back into the swing of it all. Thanks for (another) excellent course!” - Paul L.
“Huge help to be able to review these in a platform much more suited to learning than YouTube.” - Wesley F.

I used to do #napkinmath. Now I make videos and other resources to help math students understand the important stuff and pass their classes.
