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

Solution

simplify

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

Solution

sin^{4} (x)

Solution steps

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

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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

Simplify

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

= \frac{4 sin ^{4} ( x )}{2 ^{2}}

2^{2} = 4

= \frac{4 sin ^{4} ( x )}{4}

Divide the numbers:

\frac{4}{4} = 1

= sin^{4} (x)
