Integration, as we all know, is a
method to calculate areas by adding consecutive slices together. It
is one of the best ways to find the area of any curve drawn in
between the axis. You might be thinking that such a large
Integration is highly impossible to do. Integration approximation
calculator method lets you calculate the approximate answer by
using easy integration techniques.

##### Example

Let f(x)=ln(x) such that x varies
from x=1 to x=4.

The above integration is actually possible, and the actual solution
to the above integration is 2.5451774.

We can also perform the above
calculations by just calculating the value of log at every point.
Such as-

at x=1 ln(x)= ln(1) =0

at x=2 ln(x)= ln(2) = 0.693147

And so on.

**Note:** You can even divide the whole graph into smaller
slices with value even lesser than 1.
