integral of x^2e^{(5+x^3)}

\int x^{2} e^{(5 + x^{3})} d x

\frac{1}{3} e^{5 + x^{3}} + C

Solution steps

\int x^{2} e^{5 + x^{3}} d x

Apply u-substitution

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

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

Use the common integral:

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

= \frac{1}{3} e^{u}

Substitute back

u = 5 + x^{3}

= \frac{1}{3} e^{5 + x^{3}}

Add a constant to the solution

= \frac{1}{3} e^{5 + x^{3}} + C

\int sec^{2} (x) sin^{3} (x) d x

\int \frac{6 ^{x} + 1}{2 ^{x}} d x

\int d (arcsin (x)) d x

\int x x^{4} + 16 d x

\int - 3 sec^{2} (x) d x
