integral of f(g(x))

Solution

\int f (g (x))

Solution

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

Solution steps

\int f gx df

Take the constant out:

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

= gx \cdot \int fdf

Apply the Power Rule

: \frac{f ^{2}}{2}

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

Multiply fractions:

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

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

Add a constant to the solution

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