integral of x^4cos(x^5)

\int x^{4} cos (x^{5}) d x

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

Solution steps

\int x^{4} cos (x^{5}) d x

Apply u-substitution

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

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

Use the common integral:

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

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

Substitute back

u = x^{5}

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

Add a constant to the solution

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

x \to 2 lim (\frac{2}{x} + 4)

\int_{0}^{4} \frac{2}{x} d x

\int (7 e^{9 x}) d x

5^{t a n (5 x)}

\int \frac{1}{1 - 2 x + x ^{2}} d x
