WebUnlike normal solutions of algebraic equations with the number of solutions based on the degree of the variable, in trigonometric equations, the solutions are of two types, based on the different value of angle for the trigonometric function, for the same solution.For example, for a simple trigonometric equation 2Cosθ - 1 = 0, the solution is given by, Cosθ … WebDec 20, 2024 · Solution. We can solve this equation using only algebra. Isolate the expression tanx on the left side of the equals sign. 2(tanx) + 2(3) = 5 + tanx 2tanx + 6 = 5 + tanx 2tanx − tanx = 5 − 6 tanx = − 1. There are two angles on the unit circle that have a tangent value of − 1: θ = 3π 4 and θ = 7π 4.
