High School Math Solutions – Trigonometry Calculator, Trig Equations. The first solution, cot(x) = 0, is already simplified, but we have to do a little more with the second one: Since cot(x) is the reciprocal of tan(x), it will be 0 every time tan(x) is undefined (0/1 instead of 1/0). © copyright 2003-2021 Study.com. We look for known patterns, factor, find common denominators, and substitute certain expressions with a variable to make solving a more straightforward process. With those concepts in mind, let's get to solving trig equations. Trigonometric operations are also discussed, and students also learn about trigonometric equations, including how to understand, set up, and factor trig equations, how to solve individual trigonometric equations, as well as systems of trigonometric equations, how to find trig roots, and how to use the quadratic formula on trigonometric equations.

Therefore, x = π 4,x = π − π 4 = 3 π 4,x = π + π 4 = 5 π, and x 4 = 2 π − π 4 = 7 π 4 within [0, 2π). An angle is a measure of rotation, and if you keep rotating you'll get more angles with the same sine. Practise anywhere, anytime, and on any device! When you're solving trig equations, you're looking for x (or some other value), using trig identities and the rules of algebra.
