3x 7 28

Use trig identity to transform (cos x + cos 3x): F(x) = 2cos 2x.cos x + cos 2x = cos 2x(2cos x + 1 ) = 0. Next, solve the 2 basic trig equations. 2. Transform a trig equation F(x) that has many trig functions as variable, into a equation that has only one variable. The common variables to be chosen are: cos x, sin x, tan x, and tan (x/2).
