What is an integral?

890 views

I’m in CalcII now and for the life of me cannot wrap my head around integrals. Now we are using things like u-Substitution methods and solving the areas between 2 curves. I can understand how the equations work, but not why because I still cannot picture what an integral is or why it’s important.

Integrals are a supercharged multiplication technique that allows you to multiply numbers that change. Doing this manually is very difficult and requires a lot of practice.

*e.g. the area under the curve of 2×2 is a box with area 4, with integrals it’s a much fancier shape
