Solving Trig Equations Using Inverses (15 Helpful Examples!) from calcworkshop.com
When solving trig equations with multiple angles between 0 and , we’ll typically get fewer solutions if the coefficient of the variable is less than 1, or more solutions if the coefficient of the variable is greater than 1. Solve the trig equation for all values of x. A sin (a) = b sin (b) = c sin (c) when there is an angle opposite a side, this equation comes to the rescue.

Let’s just jump into the examples and see how to solve trig equations. Solving basic trig equations proceeds by studying the various positions of the arc x on the trig circle, and by using trig conversion table (or calculator). Law of sines (the sine rule):
Solve Sin X = 0.
