Indefinite integrals are the integrals whose limits of integration are not given. So for indefinite integrals, we only evaluate the integral and get the final answer in terms of the variable itself. Indefinite integral calculator is the online tool which can instantly give the answer for the integral.


Example 1: Evaluate the indefinite integral for the function, f(x) = 4x2

The integral notation for the given function: ∫(4x2)dx

The above integral is an indefinite integral because; the limits of integration are not mentioned here.

We apply the Power rule of Integration -> ∫xn dx= x(n+1)/ (n+1) + c where ‘c’ is a constant!

Following this rule, we can apply the above formula for the function.

We get -> ∫(4x2)dx = 4 * (x2+1)/ (2 + 1) + c

->∫(4x2)dx = 4x3/3 + c

 
Example 2: Evaluate the indefinite integral for the function, f(x) = 5x3

The integral notation for the given function: ∫(5x3)dx

The above integral is an indefinite integral because; the limits of integration are not mentioned here.

We apply the Power rule of Integration -> ∫xn dx= x(n+1)/ (n+1) + c where ‘c’ is a constant!

We can apply the above formula for the function,

We get -> ∫(5x3)dx = 5 * (x3+1)/ (3 + 1) + c

∫(5x3)dx = 5x4/4 + c
