WebSolve the equation exactly: tan(θ − π 2) = 1, 0 ≤ θ < 2π. Solution Recall that the tangent function has a period of π. On the interval [0, π) ,and at the angle of π 4 ,the tangent has a value of 1. However, the angle we want is (θ − π 2). Thus, if tan(π 4) = 1 ,then θ − π 2 = π 4 θ = 3π 4 ± kπ Over the interval [0, 2π) ,we have two solutions: WebAnswer (1 of 6): Here are a couple of handy reference tables for you. from Trigonometric Equations What is sin(cosθ)? * In radians: * * where θ = 1 * cos(1) = 0.54030230586 * …
