integral of 5xsin(3-2x)

\int 5 x sin (3 - 2 x) d x

5 (\frac{1}{2} x cos (3 - 2 x) + \frac{1}{4} sin (3 - 2 x)) + C

Solution steps

\int 5 x sin (3 - 2 x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 5 \cdot \int x sin (3 - 2 x) d x

Apply Integration By Parts

= 5 (\frac{1}{2} x cos (3 - 2 x) - \int \frac{1}{2} cos (3 - 2 x) d x)

\int \frac{1}{2} cos (3 - 2 x) d x = - \frac{1}{4} sin (3 - 2 x)

= 5 (\frac{1}{2} x cos (3 - 2 x) - (- \frac{1}{4} sin (3 - 2 x)))

Simplify

= 5 (\frac{1}{2} x cos (3 - 2 x) + \frac{1}{4} sin (3 - 2 x))

Add a constant to the solution

= 5 (\frac{1}{2} x cos (3 - 2 x) + \frac{1}{4} sin (3 - 2 x)) + C

\int n a^{c o s (b x)} sin (b x) d x

\int 9 x e^{- 4 x^{2}} d x

\int cot^{3} (2 t) d t

\int - 0.5 e^{- 0.01 x} d x

\int \frac{1}{( 1 - x ^{3} )} d x
