So integration is the sum of what the one bit you have would make across a large area… the integral of a brick is a wall. That was the most useful analogy I heard in college regarding math.
I will just expand this further just integrant is just counting the area of the bricks to get the wall area and differential equations are just functions that will give you area of the wall given number of bricks
It would be so much easier if integration was explained this way instead of making people either learn the proof that newton did, or offer boob-related services for an explanation.
Every time I see one of your pictures I say “holy fuck”
The thing with integrals is knowing your boundaries… I’d say those are sizeable bookends to what’s in between!
