sin 2x = 2 sin x cos x. Double-angle identity for sine. • There are three types of double-angle identity for cosine, and we use sum identity for cosine, first: cos (x +   Sin 2x Cos 2x is one such trigonometric identity that is important to solve a variety of trigonometry questions. (image will be uploaded soon). Sine (sin): Sine  cos x ctg x = cos x sin x sin 2x = 2 sinxcosx cos 2x = cos2 x − sin2 x sin2 x = 1− cos 2x. 2 cos2 x = 1+cos 2x.

cos 2x = 1 − 2 sin2x. The determinant of this matrix is w= -2 Sin^2 [2x] -2 Cos^2 [2x] = -2 Since the Wronsky determinant W differs from zero, the functions are linearly independent. Wronsky determinant that differs from zero is a sufficient condition of linear independence (and in many cases also necessary, but not always).
