$$\int\limits_{0}^{1} x^{3} e^{x^{2}}\, dx$$

Integral(x^3*exp(x^2), (x, 0, 1))

Detail solution

Let $u = x^{2}$ .

Then let $du = 2 x dx$ and substitute $\frac{du}{2}$ :

$\int \frac{u e^{u}}{2}\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int u e^{u}\, du = \frac{\int u e^{u}\, du}{2}$
  1. Use integration by parts:
    
    $\int \operatorname{u} \operatorname{dv} = \operatorname{u}\operatorname{v} - \int \operatorname{v} \operatorname{du}$
    
    Let $u{\left(u \right)} = u$ and let $\operatorname{dv}{\left(u \right)} = e^{u}$ .
    
    Then $\operatorname{du}{\left(u \right)} = 1$ .
    
    To find $v{\left(u \right)}$ :
    1. The integral of the exponential function is itself.
      
      $\int e^{u}\, du = e^{u}$
    Now evaluate the sub-integral.
  2. The integral of the exponential function is itself.
    
    $\int e^{u}\, du = e^{u}$
  So, the result is: $\frac{u e^{u}}{2} - \frac{e^{u}}{2}$
Now substitute $u$ back in:

$\frac{x^{2} e^{x^{2}}}{2} - \frac{e^{x^{2}}}{2}$
Now simplify:

$\frac{\left(x^{2} - 1\right) e^{x^{2}}}{2}$
Add the constant of integration:

$\frac{\left(x^{2} - 1\right) e^{x^{2}}}{2}+ \mathrm{constant}$

The answer is:

$\frac{\left(x^{2} - 1\right) e^{x^{2}}}{2}+ \mathrm{constant}$
