integral of h^3e^{h^2}

\int h^{3} e^{h^{2}} d h

\frac{1}{2} (e^{h^{2}} h^{2} - e^{h^{2}}) + C

Solution steps

\int h^{3} e^{h^{2}} d h

Apply u-substitution

: \int \frac{e ^{u^{\frac{2}{3}}} u ^{\frac{1}{3}}}{3} d u

= \int \frac{e ^{u^{\frac{2}{3}}} u ^{\frac{1}{3}}}{3} 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 e^{u^{\frac{2}{3}}} u^{\frac{1}{3}} d u

Apply u-substitution

: \int \frac{3 e ^{v} v}{2} d v

= \frac{1}{3} \cdot \int \frac{3 e ^{v} v}{2} d v

Take the constant out:

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

= \frac{1}{3} \cdot \frac{3}{2} \cdot \int e^{v} v d v

Apply Integration By Parts

: e^{v} v - \int e^{v} d v

= \frac{1}{3} \cdot \frac{3}{2} (e^{v} v - \int e^{v} d v)

\int e^{v} d v = e^{v}

= \frac{1}{3} \cdot \frac{3}{2} (e^{v} v - e^{v})

Substitute back

= \frac{1}{3} \cdot \frac{3}{2} (e^{(h^{3})^{\frac{2}{3}}} (h^{3})^{\frac{2}{3}} - e^{(h^{3})^{\frac{2}{3}}})

Simplify

\frac{1}{3} \cdot \frac{3}{2} (e^{(h^{3})^{\frac{2}{3}}} (h^{3})^{\frac{2}{3}} - e^{(h^{3})^{\frac{2}{3}}}) : \frac{1}{2} (e^{h^{2}} h^{2} - e^{h^{2}})

= \frac{1}{2} (e^{h^{2}} h^{2} - e^{h^{2}})

Add a constant to the solution

= \frac{1}{2} (e^{h^{2}} h^{2} - e^{h^{2}}) + C

\int (3 x + 7) d x

\int \frac{x ^{4} - 6}{x ^{3} - 2 x ^{2}} d x

\int (x^{a} - x^{- a})^{2} d x

\int \frac{1 - x ^{2}}{1 + x ^{2}} d x
