The sin 2x formula is the double angle identity used for the sine function in trigonometry. It is sin 2x = 2sinxcosx and sin 2x = (2tan x) /(1 + tan^2x). On the other hand, sin^2x identities are sin^2x - 1- cos^2x and sin^2x = (1 - cos 2x)/2.
Sin squared, written as $\sin^2(x)$, is the square of the sine function, often used in trigonometry, physics, and engineering.
