expand (1-cos(x))cos(x)

expand

(1 - cos (x)) cos (x)

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

Solution steps

(1 - cos (x)) cos (x)

= cos (x) (1 - cos (x))

Apply the distributive law:

a (b - c) = ab - a c

cos (x) (1 - cos (x)) = cos (x) \cdot 1 - cos (x) cos (x)

= cos (x) \cdot 1 - cos (x) cos (x)

Simplify

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

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

(x - 6) (x + 6)

(1 + sin (a)) \cdot (1 - sin (a))

(- 15 - - 9) - (3 - - 9)

\frac{2 ( s + 8 )}{s ^{2} + 4 s + 13}

(x^{2} - 2 x - 8) e^{x}
