In this video we'll talk about how to use trigonometric identities, including reciprocal identities to prove that a trigonometric equation is true.
All of the examples we'll do are true equations, where the left side of the equation is equal to the right side of the equation. But the left and right sides look so different that we really can't see that they're actually equal to one another, until we do some manipulation. We'll use the relationships between the trig functions to change both sides of the equation until they match each other. Once we get them to match, that's when we'll know that the equation is true.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
