WebOct 18, 2015 · Express sin (x/2) in terms of cos x. Ans: sin (x /2) = sqrt((1 - cos x)/2) By applying the trig identity: cos 2a = 1 - 2sin^2 a, we get: cos x = 1 - 2sin^2 (x/2) 2sin^2 (x/2) = 1 - cos x sin^2 (x/2) = (1 - cos x)/2 sin (x/2) = +- sqrt((1 - cos x)/2) WebThe graph of y=sin(x) is like a wave that forever oscillates between -1 and 1, in a shape that repeats itself every 2π units. Specifically, this means that the domain of sin(x) is all real numbers, and the range is [-1,1]. See how …

WebUsing one of the trigonometric identities, we have sin 2 x + cos 2 x = 1. Subtracting cos 2 x from both sides, we get sin 2 x = 1 - cos 2 x. Thus, one of the sin squared x formulas is, sin2 x = 1− cos2x sin 2 x = 1 − cos 2 x. Using one of the double angle formulas of cosine function, we have cos 2x = 1 - 2 sin 2 x. Web6.
