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 $\sin^2 x$: $$\sin^2 x = (\sin x)^2 = \frac12 (1 - \cos (2 x)).$$ We can see this using the double-angle formula for cosines

. constitutes an orthogonal system of functions on the interval [– π, π]. Sin 2x Cos 2x = 2 Cos x (2 Sin x Cos 2 x − Sin x)Or, Sin 2x Cos 2x = 2 Cos x (Sin x – 2 Sin 3 x) How to Derive Sin 2x Cos 2x Value? To find the value of sin2x × Cos 2x, the trigonometric double angle formulas are used. For the derivation, the values of sin 2x and cos 2x are used. sin(2x) - (cos(x))^2 = 0,88.

Write ln x as ln(x) 5 Sin^2 x is “sine-squared of x” which is a different function from the sine function. Sin x^2 means square of the angle and the sine of it..i.e.
