integral of fx

Solution

\int f x d x

Solution

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

Solution steps

\int f x d x

Take the constant out:

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

= f \cdot \int x d x

Apply the Power Rule

: \frac{x ^{2}}{2}

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

Multiply fractions:

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

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

Add a constant to the solution

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