integral of x^3sin(5x)

\int x^{3} sin (5 x) d x

- \frac{1}{5} x^{3} cos (5 x) + \frac{3}{625} (25 x^{2} sin (5 x) - 2 (- 5 x cos (5 x) + sin (5 x))) + C

Solution steps

\int x^{3} sin (5 x) d x

Apply Integration By Parts

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

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

\int - \frac{3}{5} x^{2} cos (5 x) d x = - \frac{3}{625} (25 x^{2} sin (5 x) - 2 (- 5 x cos (5 x) + sin (5 x)))

= - \frac{1}{5} x^{3} cos (5 x) - (- \frac{3}{625} (25 x^{2} sin (5 x) - 2 (- 5 x cos (5 x) + sin (5 x))))

Simplify

= - \frac{1}{5} x^{3} cos (5 x) + \frac{3}{625} (25 x^{2} sin (5 x) - 2 (- 5 x cos (5 x) + sin (5 x)))

Add a constant to the solution

= - \frac{1}{5} x^{3} cos (5 x) + \frac{3}{625} (25 x^{2} sin (5 x) - 2 (- 5 x cos (5 x) + sin (5 x))) + C

\int x \cdot sin (\frac{x}{2}) d x

0.72 x^{3} - 4.8 x^{2} + 0.6 x + 7.6

\int_{- 1}^{1} e^{x} - (x^{2} - 2) d x

\frac{\partial}{\partial x} (\frac{2 x - y}{x + 2 y})

\frac{\partial ^{2}}{\partial x ^{2}} (x^{2} - y^{2})
