Integral of y=kx^2 dx

The solution

$$\int\limits_{4}^{1} k x^{2}\, dx$$

Integral(k*x^2, (x, 4, 1))

Detail solution

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

$\int k x^{2}\, dx = k \int x^{2}\, dx$
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x^{2}\, dx = \frac{x^{3}}{3}$
So, the result is: $\frac{k x^{3}}{3}$
Add the constant of integration:

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

The answer is:

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