For the following exercises, find the exact values of a) sin(x2), b) cos(x2), and c) tan(x2) without solving for x, when 0∘≤x≤360∘ 1. If sin x=, and x is in quadrant III.
2.If sec x=−4, and x is in quadrant II.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
