integral of x/(x^2+10)

\int \frac{x}{x ^{2} + 10} d x

\frac{1}{2} ln x^{2} + 10 + C

Solution steps

\int \frac{x}{x ^{2} + 10} d x

Apply u-substitution

: \int \frac{1}{2 u} d u

= \int \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} ln ∣ u ∣

Substitute back

u = x^{2} + 10

= \frac{1}{2} ln x^{2} + 10

Add a constant to the solution

= \frac{1}{2} ln x^{2} + 10 + C

\int \frac{3 x}{x ^{2} + 4 x + 5} d x

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

\int 8 x (2 x - 1)^{4} d x

\int cos^{3} (x) + sin^{3} (x) d x

\int 5^{\frac{3}{4}} d x
