As many people have pointed out by now, $\sin^2 x$ is simply a "nickname" for $(\sin x)^2$. Therefore, $\sin^2\ 30 = (\sin 30)^2 = (1/2)^2 = 1/4$. As it happens, though, there is another useful thing we can say about $\sin^2 x$:

6 cze 2024 · Sin 2 x Formula. For the derivation of the sin 2 x formula, we use the trigonometric identities sin 2 x + cos 2 x = 1 and the double angle formula of cosine function cos 2x = 1 – 2 sin 2 x. Using these identities, sin 2 x can be expressed in terms of cos 2 x and cos2x. Let us derive the formulas: Sin 2 x Formula in Terms of Cos x
