# Interactive video lesson plan for: How do you find all SIX of the TRIG FUNCTIONS? (KristaKingMath)

#### Activity overview:

► My Trigonometry course: https://www.kristakingmath.com/trigonometry-course

The six circular trig functions are sine, cosine, tangent, cosecant, secant, and cotangent. You can find the value of all of them if you only know the value of one of them, plus the quadrant that contains the angle.

In order to find these values, you'll need to be able to identify the four quadrants of the cartesian coordinate plane, so that you can locate the angle.

The trick SOH-CAH-TOA (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent) will let you build out a triangle that contains the angle theta, and then you'll be able to easily find sine, cosine and tangent, then use reciprocal identities to find their reciprocals, cosecant, secant and cotangent.

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.
