Sin2x is equal to

WebbAnswer (1 of 15): You are probably aware of the classic trig identity \cos^{2}x+\sin^{2}x=1 which we can write as \cos^{2}x=1-\sin^{2}x=(1+\sin x)(1-\sin x) From this we can find 1+\sin x 1+\sin x = \frac{\cos^{2}x}{1-\sin x} \tag 1 Equation (1) is a “formula” for 1+\sin x but certainly not... WebbSin2x = (2tan x) / (1 + tan2x) These are the primary Sin2x formulae. Using the trigonometric equation Sin2x + cos2x = 1, this expression may be expressed in terms of sin x (or cos x) alone. This trigonometric identity allows us to write sinx = √(1 – cos2x) and cosx =. √(1 – Sin2x). Therefore, the formula for Sin2x given cos and sin are:
