Does anyone on here not really get a topic until they come back to it atleast like a week or two later. I like read something and then most of the time I have no clue what it is, or I struggle to get by it, but then if I try it again a few weeks later, I get it and it seems a lot more straight forward. THe most recent example is solids of revolutions and work based on the integrals of density and height functions.
Other examples, which got me a lot more lost
modular congruences, euler and hamilton graphs.
Im hoping that if I ever go back to it, I will have the slightest clue about "linear nonhomogeneous recurrence relations with constant coefficients"
