How to solve a trig function
WebOct 28, 2024 · If a trig equation can be solved analytically, these steps will do it: Put the equation in terms of one function of one angle . Write the equation as one trig function of an angle equals a constant . Write down the possible value (s) for the angle . If necessary, solve for the variable . Apply any restrictions on the solution . WebMar 26, 2016 · Solve cos 2 x + cos x + 1 = 0 for x between 0 and 2 p. Replace cos 2 x with 2cos 2 x – 1. This version of the cosine double-angle identity is preferable because the other trig function in the equation already has a cosine in it. Simplify the equation. Then factor out cos x. Set each factor equal to 0.
