MATH 2412 ? PRECALCULUS Section 7.4-7.5 Trigonometric Equations

. Please review Section 7.4-7.5. Work all examples in the text. Ex: Solve sec2 x - 2 = 0.

Ex: Solve sec2 (3x) - 2 = 0.

Ex: Solve sin (2x) + cos x = 0. Ex: Solve 2 cos2 x + sin x = 1.

MATH 2412 Ex: Solve 2 cos (2x) - 1 = 0

Section 7.4-7.5 Continued

Ex: Solve 2 sin x tan x - tan x = 1 - 2 sin x on the interval [0, 2).
