Lesson 10: Solving Trigonometric Equations Using The Unit Circle


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
