What is an integral?

1.04K 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.

Lots of great answers here. I’ll give you some resources instead.

Khan Academy is awesome it got me thru calc 1-4 (calc 2 and 4 two times… lol)

3blue1brown provides some great visualization of calculus concepts you may find useful.

You got this. If you fail, try again. I failed calc 2 and 4 my first time thru, I’m now a successful engineer. It didn’t matter at all. These are extremely complicated concepts that 90% of people will never understand.
