Lesson 10: Solving Trigonometric Equations Using The Unit Circle

07/15/2016

Lesson on solving for trigonometric equations using the trigonometric identities. Solving for the value of the angles in the trigonometric equations is similar to solving for the value of x in algebra but with added steps. These added steps require the understanding of trigonometric functions and trigonometric identities. 

4:09 Solve for sinx + sqrt 2 = -sinx
5:58 Solve for secxcscx = cscx 
8:59 Solve 2cos^2 x + cosx -- 1 = 0
