integral of x^2sinh(x^3)

\int x^{2} sinh (x^{3}) d x

\frac{1}{3} cosh (x^{3}) + C

Solution steps

\int x^{2} sinh (x^{3}) d x

Apply u-substitution

= \int \frac{sinh ( 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 sinh (u) d u

Use the common integral:

\int sinh (u) d u = cosh (u)

= \frac{1}{3} cosh (u)

Substitute back

u = x^{3}

= \frac{1}{3} cosh (x^{3})

Add a constant to the solution

= \frac{1}{3} cosh (x^{3}) + C
