Solved example of integral calculus
The integral of a function times a constant ($3$) is equal to the constant times the integral of the function
Apply the power rule for integration, $\displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}$, where $n$ represents a number or constant function, such as $2$
Any expression multiplied by $1$ is equal to itself
As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
