The given trigonometric expression: tan x 2 = cosec x - sin x. It is known that, sin θ = 2 tan θ 2 1 + tan 2 θ 2. Thus, tan x 2 = cosec x - sin x. ⇒ tan x 2 = 1 sin x - sin x ∵ cosec θ = 1 sin θ ⇒ tan x 2 = 1 + tan 2 x 2 2 tan x 2 - 2 tan x 2 1 + tan 2 x 2. Let us assume that m = tan x 2.
Webcos^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. some other identities (you will learn later) include -. cos x/sin x = cot x. 1 + tan^2 x = sec^2 x. 1 + cot^2 x = csc^2 x. hope this helped!

WebExpert Answer. The German mathematician Karl Weierstrass (1815-1897) noticed that the substitution t=tan (x/2) will convert any rational function of sin (x) and cos (x) into an ordinary rational function of t. If t = tan (2/2), -1 < x < 7, then it can be shown that = 2 1 C t COS - sin () 2 2 (1 + t2' V1 + t2 2t cos (x) 1 - 2 1+ t2' sin (2) 1 ...
