1-116.

Calculus problems often require using one or more of the trigonometric identities to solve problems. Solve each of the following equations where

*x*∈ [0, 2π]. Use exact values. Homework Help ✎tan

*x*· csc*x*= 22 sin

^{2}*x*− cos*x*− 1 = 0tan

*x*+ cot*x*= −2

Simplify the left side of the equation to solve for x.
