Question

how we integrate any equation?​

Answer 1

heya,

Integration is a way of adding slices to find the whole.

Integration can be used to find areas, volumes, central points and many useful things. But it is easiest to start with finding the area under the curve of a function like this:

integral area = ?

What is the area under y = f(x) ?

Slices

We could calculate the function at a few points and add up slices of width Δx like this (but the answer won't be very accurate):

integral area big deltax

We can make Δx a lot smaller and add up many small slices (answer is getting better):

integral area small deltax

And as the slices approach zero in width, the answer approaches the true answer.

We now write dx to mean the Δx slices are approaching zero in width.

might help u!!!

thanks!!!
