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

Integral(x/E^(3*x^2), (x, 0, 1))

Detail solution

Let $u = e^{- 3 x^{2}}$ .

Then let $du = - 6 x e^{- 3 x^{2}} dx$ and substitute $- \frac{du}{6}$ :

$\int \frac{1}{36}\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \left(- \frac{1}{6}\right)\, du = - \frac{\int 1\, du}{6}$
  1. The integral of a constant is the constant times the variable of integration:
    
    $\int 1\, du = u$
  So, the result is: $- \frac{u}{6}$
Now substitute $u$ back in:

$- \frac{e^{- 3 x^{2}}}{6}$
Add the constant of integration:

$- \frac{e^{- 3 x^{2}}}{6}+ \mathrm{constant}$

The answer is:

$- \frac{e^{- 3 x^{2}}}{6}+ \mathrm{constant}$
