Integral of 3*x^3 dx

The solution

You have entered [src]

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

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

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int 3 x^{3}\, dx = 3 \int x^{3}\, dx$
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x^{3}\, dx = \frac{x^{4}}{4}$
So, the result is: $\frac{3 x^{4}}{4}$
Add the constant of integration:

$\frac{3 x^{4}}{4}+ \mathrm{constant}$

The answer is:

$\frac{3 x^{4}}{4}+ \mathrm{constant}$
