Take the inverse sine of both sides of the equation to extract θ θ from inside the sine. θ = arcsin(1) θ = arcsin ( 1) … WebJul 12, 2024 · Answer. In addition to the Pythagorean Identity, it is often necessary to rewrite the tangent, secant, cosecant, and cotangent as part of solving an equation. Example 7.1. 4. Solve tan ( x) = 3 sin ( x) for all solutions with 0 ≤ x < 2 π. Solution. With a combination of tangent and sine, we might try rewriting tangent.
