integral of x^2sin(5x)

\int x^{2} sin (5 x) d x

- \frac{1}{5} x^{2} cos (5 x) + \frac{2}{125} (5 x sin (5 x) + cos (5 x)) + C

Solution steps

\int x^{2} sin (5 x) d x

Apply Integration By Parts

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

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

\int - \frac{2}{5} x cos (5 x) d x = - \frac{2}{125} (5 x sin (5 x) + cos (5 x))

= - \frac{1}{5} x^{2} cos (5 x) - (- \frac{2}{125} (5 x sin (5 x) + cos (5 x)))

Simplify

= - \frac{1}{5} x^{2} cos (5 x) + \frac{2}{125} (5 x sin (5 x) + cos (5 x))

Add a constant to the solution

= - \frac{1}{5} x^{2} cos (5 x) + \frac{2}{125} (5 x sin (5 x) + cos (5 x)) + C

e^{x} - x^{e}

\frac{s}{( s + 1 ) ( s ^{2} + 1 )}

\int (\frac{3 w ^{2}}{2} - \frac{2}{3 w ^{2}}) d w

\int x^{2} 2 + 9 x^{2} d x

y^{^{''}} - 7 y^{^{'}} + 12 y = 6 e t
