expand (1-cos(12x))^2

expand

(1 - cos (12 x))^{2}

1 - 2 cos (12 x) + cos^{2} (12 x)

Solution steps

(1 - cos (12 x))^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(1 - cos (12 x))^{2} = 1^{2} - 2 \cdot 1 \cdot cos (12 x) + cos^{2} (12 x)

= 1^{2} - 2 \cdot 1 \cdot cos (12 x) + cos^{2} (12 x)

Simplify

1^{2} - 2 \cdot 1 \cdot cos (12 x) + cos^{2} (12 x) : 1 - 2 cos (12 x) + cos^{2} (12 x)

= 1 - 2 cos (12 x) + cos^{2} (12 x)

\frac{x ^{2} - 3 x - 4}{( x - 1 ) ( x + 2 ) ^{2}}

- 36 h (8 h - h^{2})

V^{2} + 2 a (x - y)

42 + 36

\frac{1}{2} (arcsin (x - 1) + \frac{1}{2} sin (2 arcsin (x - 1)))
