Solving integrals/ 7*x

Integral of 7*x dx

The solution

You have entered [src]

$$\int\limits_{1}^{3} 7 x\, dx$$

Integral(7*x, (x, 1, 3))

Detail solution

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

$\int 7 x\, dx = 7 \int x\, dx$
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x\, dx = \frac{x^{2}}{2}$
So, the result is: $\frac{7 x^{2}}{2}$
Add the constant of integration:

$\frac{7 x^{2}}{2}+ \mathrm{constant}$

The answer is:

$\frac{7 x^{2}}{2}+ \mathrm{constant}$
