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 $\sin^2 x$:
product representations sinx; osculating circle of y = sin(x) at x = pi/4; integrate cos(x)^2 from x = 0 to 2pi

To derive the sin 2 x formula, we will use the trigonometric identities sin 2 x + cos 2 x = 1 and the double angle formula of cosine function given by cos 2x = 1 - 2 sin 2 x. Using these identities, we can express the formulas of sin 2 x in terms of cos x and cos 2x.
