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

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

Detail solution

Let $u = x^{2}$ .

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

$\int \frac{e^{u}}{2}\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\text{False}$
  1. The integral of the exponential function is itself.
    
    $\int e^{u}\, du = e^{u}$
  So, the result is: $\frac{e^{u}}{2}$
Now substitute $u$ back in:

$\frac{e^{x^{2}}}{2}$
Add the constant of integration:

$\frac{e^{x^{2}}}{2}+ \mathrm{constant}$

The answer is:

$\frac{e^{x^{2}}}{2}+ \mathrm{constant}$
