$$\int\limits_{0}^{1} x^{2} e^{4 - x^{4}}\, dx$$

Integral(x^2*E^(-x^4 + 4), (x, 0, 1))

Detail solution

Rewrite the integrand:

$x^{2} e^{4 - x^{4}} = x^{2} e^{4} e^{- x^{4}}$
The integral of a constant times a function is the constant times the integral of the function:

$\int x^{2} e^{4} e^{- x^{4}}\, dx = e^{4} \int x^{2} e^{- x^{4}}\, dx$
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\frac{3 \Gamma\left(\frac{3}{4}\right) \gamma\left(\frac{3}{4}, x^{4}\right)}{16 \Gamma\left(\frac{7}{4}\right)}$
So, the result is: $\frac{3 e^{4} \Gamma\left(\frac{3}{4}\right) \gamma\left(\frac{3}{4}, x^{4}\right)}{16 \Gamma\left(\frac{7}{4}\right)}$
Now simplify:

$\frac{e^{4} \gamma\left(\frac{3}{4}, x^{4}\right)}{4}$
Add the constant of integration:

$\frac{e^{4} \gamma\left(\frac{3}{4}, x^{4}\right)}{4}+ \mathrm{constant}$

The answer is:

$\frac{e^{4} \gamma\left(\frac{3}{4}, x^{4}\right)}{4}+ \mathrm{constant}$
