integral of x^2e^{6x^3}

\int x^{2} e^{6 x^{3}} d x

\frac{1}{18} e^{6 x^{3}} + C

Solution steps

\int x^{2} e^{6 x^{3}} d x

Apply u-substitution

: \int \frac{e ^{u}}{18} d u

= \int \frac{e ^{u}}{18} d u

Take the constant out:

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

= \frac{1}{18} \cdot \int e^{u} d u

Use the common integral:

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

= \frac{1}{18} e^{u}

Substitute back

u = 6 x^{3}

= \frac{1}{18} e^{6 x^{3}}

Add a constant to the solution

= \frac{1}{18} e^{6 x^{3}} + C

\int x 8 x d x

\int t e^{- \frac{t ^{2}}{2}} d t

\int \frac{1}{( x + 8 ) ^{6}} d x

\int \frac{1}{36} (t (12 - t)) d t

\int (3 x + 5)^{99} d x
