integral of (v^2)/(v^3+100)

Solution

\int \frac{v ^{2}}{v ^{3} + 100} d v

Solution

\frac{1}{3} ln v^{3} + 100 + C

Solution steps

\int \frac{v ^{2}}{v ^{3} + 100} d v

Apply u-substitution

: \int \frac{1}{3 u} d u

= \int \frac{1}{3 u} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{3} ln ∣ u ∣

Substitute back

u = v^{3} + 100

= \frac{1}{3} ln v^{3} + 100

Add a constant to the solution

= \frac{1}{3} ln v^{3} + 100 + C
