expand 1/2-1/2 cos^2(2x)

expand

\frac{1}{2} - \frac{1}{2} cos^{2} (2 x)

\frac{1}{2} sin^{2} (2 x)

Solution steps

\frac{1}{2} - \frac{1}{2} cos^{2} (2 x)

Use the Pythagorean identity:

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

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

= \frac{1}{2} sin^{2} (2 x)

- \frac{3 ( - n - 27 π ^{3} )}{n ^{2}}

\frac{3 ( x ^{2} + 2 x + 6 )}{2}

4 x (x + 10 - 2 (x - 5) = 2^{2} - 4)

(u x^{3} - ln (x)) (x d u + u d x)

\frac{( x + 1 ) ( x + 4 )}{( x - 3 ) ( x + 5 ) ( x - 7 )}
