                Lesson 5 – Solving Linear Trigonometric Equations

        The same strategy can be used to solve linear trigonometric equations when
         the variable is measured in degrees or radians
        Because of their periodic nature, trigonometric equations have an infinite
         number of solutions, we usually get the solutions within a specific interval
        Use special triangles, sketches of the graph, etc. to help solve the equations
        NOT ALL TRIGONOMETIC EQUATIONS ARE IDENTITIES


Example 1: Solve the following equations.

a)   2 sin x  1  0,0  x  2




b)   3(tan x  1)  2,0  x  360




c)   2 sin x cos x  cos 2 x,0  x  2
