The trig identities

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. You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more. WebIn this explainer, we will focus on the its applications in trigonometry—in particular the derivations of trigonometric identities. In the first example, we will demonstrate how we can derive trigonometric identities by using one of the properties of the exponential function and then applying Euler’s formula.
