integral of f(r)

Solution

\int f (r) d r

Solution

\frac{f r ^{2}}{2} + C

Solution steps

\int f r d r

Take the constant out:

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

= f \cdot \int r d r

Apply the Power Rule

: \frac{r ^{2}}{2}

= f \frac{r ^{2}}{2}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{f r ^{2}}{2}

Add a constant to the solution

= \frac{f r ^{2}}{2} + C
