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

expand

cos (2) (t + \frac{π}{2})

cos (2) t + \frac{π}{2} cos (2)

Solution steps

cos (2) (t + \frac{π}{2})

Apply the distributive law:

a (b + c) = ab + a c

a = cos (2), b = t, c = \frac{π}{2}

= cos (2) t + cos (2) \frac{π}{2}

= cos (2) t + \frac{π}{2} cos (2)

Z (2 x - 1) d x (x - 1) (x - 2) (x - 3)

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

(e^{t} + 2 e^{2 t})^{2}

(- 2, - 11) Y (4, 7)

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