expand cos(θ)(1-cos(θ))

expand

cos (θ) (1 - cos (θ))

cos (θ) - cos^{2} (θ)

Solution steps

cos (θ) (1 - cos (θ))

Apply the distributive law:

a (b - c) = ab - a c

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

= cos (θ) \cdot 1 - cos (θ) cos (θ)

Simplify

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

= cos (θ) - cos^{2} (θ)

\frac{1}{( x + 7 ) x ^{2}}

(3 x + 2 y = 6,) (9 x + 6 y = 20)

(1 + x + x^{2})^{7}

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

sin (- \frac{π}{4}) sin (- \frac{π}{12})
