expand (1-4sin^2(b))cos(b)

expand

(1 - 4 sin^{2} (b)) cos (b)

cos (b) - 4 sin^{2} (b) cos (b)

Solution steps

(1 - 4 sin^{2} (b)) cos (b)

= cos (b) (1 - 4 sin^{2} (b))

Apply the distributive law:

a (b - c) = ab - a c

cos (b) (1 - 4 sin^{2} (b)) = cos (b) \cdot 1 - cos (b) \cdot 4 sin^{2} (b)

= cos (b) \cdot 1 - cos (b) \cdot 4 sin^{2} (b)

Simplify

cos (b) \cdot 1 - cos (b) \cdot 4 sin^{2} (b) : cos (b) - 4 sin^{2} (b) cos (b)

= cos (b) - 4 sin^{2} (b) cos (b)

(2 x + 2 y) (x + y) cos (x^{2} + 2 x y + y^{2})

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

(7 - 2) (5 + 3)

(- y e^{5} + 3 y e^{3} - y e^{7} + 4 y + 10) \cdot (5 y e^{2})

2 (x^{2} - 4 x + 4 - \frac{y}{2} = 8)
