expand cos(2)(x-pi/4)

expand

cos (2) (x - \frac{π}{4})

cos (2) x - \frac{π}{4} cos (2)

Solution steps

cos (2) (x - \frac{π}{4})

Apply the distributive law:

a (b - c) = ab - a c

a = cos (2), b = x, c = \frac{π}{4}

= cos (2) x - cos (2) \frac{π}{4}

= cos (2) x - \frac{π}{4} cos (2)

(- 3, 6) (6 x - 2 y - 15 = 0,)

π (x - 7) d x

(4 x e^{x}) (D - 1)^{2}

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

\frac{x m + y n}{x ( m + n )}
