WebFeb 1, 2024 · Before learning solving trig equations, you must know how to quickly find the arcs whose trig functions are known. Conversion values of arcs (or angles) are given by trig tables or calculators. [6] Example: After solving, get cos x = 0.732. Calculators give the solution arc x = 42.95 degree. WebSolving Trigonometric Equations Using Fundamental Identities. While algebra can be used to solve a number of trigonometric equations, we can also use the fundamental identities because they make solving equations simpler. Remember that the techniques we use for solving are not the same as those for verifying identities.
