integral of x^9cos(x^5)

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

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

Solution steps

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

Apply u-substitution

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

= \int \frac{u cos ( 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 cos (u) d u

Apply Integration By Parts

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

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

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

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

Substitute back

u = x^{5}

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

Simplify

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

Add a constant to the solution

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

\int (4 csc (x) cot (x) + 2 sec^{2} (x)) d x

f (x) = \frac{1}{x ^{3}}

f (x) = 20 x^{2} + 14 x - 2 x^{2}

- 12 x cos (x^{2}) + 8 x^{3} sin (x^{2})

\frac{d}{d x} (arccos (\frac{10}{x}))
