expand (x^2+6x)cos(x)dx

expand

(x^{2} + 6 x) cos (x) d x

x^{2} cos (x) d x + 6 x cos (x) d x

Solution steps

(x^{2} + 6 x) cos (x) d x

= cos (x) (x^{2} + 6 x) d x

Apply the distributive law:

a (b + c) = ab + a c

a = cos (x) d x, b = x^{2}, c = 6 x

= cos (x) d x x^{2} + cos (x) d x \cdot 6 x

= x^{2} cos (x) d x + 6 x cos (x) d x

(y^{'} (x) - 2 y) (2 - 2 x)

ro t a c i o na l (x^{2}, 3 x z^{2}, - 2 x z)

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

\frac{n ( 3 n + 1 )}{2}

6 + 5 (m + 1 = 26)
