prove sin^2(wt)=(1-cos(2wt))/2

prove

sin^{2} (wt) = \frac{1 - cos ( 2 wt )}{2}

True

Solution steps

sin^{2} (wt) = \frac{1 - cos ( 2 wt )}{2}

Manipulating right side

\frac{1 - cos ( 2 wt )}{2}

Rewrite using trig identities

= sin^{2} (wt)

We showed that the two sides could take the same form

\Rightarrow True

sin^{2} (Q) + cos^{2} (Q) = 1

sin (u) (csc (u) - csc (u)) = cos^{2} (u)

\frac{sec ( β )}{tan ( β ) + cot ( β )} = sin (β)

cos^{4} (x) - sin^{4} (x) = 1 - 2 cos^{2} (x)

sin (t) = cos (t - \frac{π}{2})
