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.
• know how to differentiate all the trigonometric functions, • know expressions for sin2θ, cos2θ, tan2θ and use them in simplifying trigonometric functions, • know how to reduce expressions involving powers and products of trigonometric func-tions to simple forms which can be integrated.
List of trigonometric identities. In mathematics, trigonometric identities. are equalities that involve trigonometric functions and are true for every single value of the occurring variables. Geometrically, these are identities involving certain functions of one or more angles.
Trig Cheat Sheet. Definition of the Trig Functions. Right triangle definition. For this definition we assume that. < q. p. 0 < or 0 ° < q < 90 ° . 2. hypotenuse opposite. q. adjacent. Unit circle definition. For this definition q is any angle. y. ( x , y ) q x. opposite. sin q = hypotenuse. q = adjacent. cos hypotenuse. q opposite. tan = adjacent.
