In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are identities potentially involving angles but also involving side lengths … WebMar 26, 2016 · Multiply the numerator and denominator of the fraction on the left by the conjugate of the denominator. The two denominators multiplied together are the difference of two squares. Replace sec 2 x in the denominator with its equivalent by using the Pythagorean identity. Simplify the denominator by canceling out the two opposites. WebBasically, If you want to simplify trig equations you want to simplify into the simplest way possible. for example you can use the identities -. cos^2 x + sin^2 x = 1. sin x/cos x = tan x.
