integral of x^9sin(x^5)

\int x^{9} sin (x^{5}) d x

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

Solution steps

\int x^{9} sin (x^{5}) d x

Apply u-substitution

: \int \frac{u sin ( u )}{5} d u

= \int \frac{u sin ( u )}{5} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int u sin (u) d u

Apply Integration By Parts

: - u cos (u) - \int - cos (u) d u

= \frac{1}{5} (- u cos (u) - \int - cos (u) d u)

\int - cos (u) d u = - sin (u)

= \frac{1}{5} (- u cos (u) - (- sin (u)))

Substitute back

u = x^{5}

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

Simplify

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

Add a constant to the solution

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

\int 3 x - x d x

\int \frac{7 x - 5}{x ^{2} - x - 2} d x

\int x^{3} 5^{x} d x

\int \frac{x ^{4}}{x ^{2} - 2} d x

\int cos^{7} (x) sin^{4} (x) d x
