How do you simplify #(1- tan^2θ) /( 1+ tan^2 θ)#? - Socratic
Mar 25, 2018 · How do you simplify 1 − tan2θ 1 + tan2θ? 1 − tan2θ sec2θ = Split the numerator: 1 sec2θ − tan2θ sec2θ = cos2θ − sin2θ cos2θ ⋅ cos2θ = cos2θ −(1 −cos2θ) = 2cos2θ − 1 = cos2θ. using the trigonometric identities. ∙ xtanθ = sinθ cosθ. ∙ xsin2θ +cos2θ = 1. ∙ xcos2θ −sin2θ = cos2θ. ⇒ 1 − tan2θ 1 + tan2θ. = 1 − sin2θ cos2θ 1 + sin2θ cos2θ × cos2θ cos2θ.

Trigonometric Identities - Math is Fun
For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. When we divide Sine by Cosine we get: So we can say: That is our first Trigonometric Identity.
