expand cos(2)(x+pi/2)

expand

cos (2) (x + \frac{π}{2})

cos (2) x + \frac{π}{2} cos (2)

Solution steps

cos (2) (x + \frac{π}{2})

Apply the distributive law:

a (b + c) = ab + a c

a = cos (2), b = x, c = \frac{π}{2}

= cos (2) x + cos (2) \frac{π}{2}

= cos (2) x + \frac{π}{2} cos (2)

(2 x + 3) d x + (2 y - 2) d y

sin (x (a + b)) + sin (x (a - b))

ln (\frac{y}{z})

\frac{3 x ^{2} - 8 ( y + 2 )}{2 y}

(1 + y^{2}) d x + (x y) d y
