Fundamental trig identity. cos(. (cos x)2 + (sin x)2 = 1. 1 + (tan x)2 = (sec x)2 (cot x)2 + 1 = (cosec x)2.
This unit is designed to help you learn, or revise, trigonometric identities. You need to know these identities, and be able to use them confidently. They are used in many different branches of mathematics, including integration, complex numbers and mechanics. The best way to learn these identities is to have lots of practice in using them. So we
