expand (cos(nx)(x+pi))dx

expand

(cos (n x) (x + π)) d x

x cos (n x) d x + π cos (n x) d x

Solution steps

(cos (n x) (x + π)) d x

Remove parentheses:

(a) = a

= cos (n x) (x + π) d x

Apply the distributive law:

a (b + c) = ab + a c

a = cos (n x) d x, b = x, c = π

= cos (n x) d xx + cos (n x) d x π

= x cos (n x) d x + π cos (n x) d x

\frac{132}{4}

0.5 (3 x - 2 y + 4 z = 11)

- 2 (x + 3) (x - 3) + 3 (x^{2} = 2 x + 1)

7 x \cdot 3 y

\frac{c _{1} - 2 x}{x ( x + 2 )}
