Throughout my thesis, I have reinvented the wheel so many times. How do I avoid reinventing the wheel? I am running out of time to have something novel. My supervisor is not helping me avoid inventing the wheel, but just leaving me to keep reinventing wheels. I need to learn myself how to stop reinventing wheels....

To anyone who's trying to relearn math all the way from precalculus, or if you would just like to review, I suggest prof. Leonard's courses:

https://m.youtube.com/@ProfessorLeonard

He teaches pre algebra all the way to calc3 in a simple, concise sort of way, focusing on concepts instead of only memorizing equations.

Unfortunately, he's inactive now, but the material is still there.

Potentially dumb math question ahead:

Would it not be possible to extend induction beyond Integers simply by taking the limit of your step value to zero?

If the logic is "if it works for n and n+1, it must work everywhere", then would the same logic not hold for "if it works for n and n+ [an infinitely small number], then it must work for all Reals?"?

This is pretty much how we check function continuity right?

I don't understand diagonalization proofs. Straight up. How does adding one to the diagonal list of numbers to make a new number prove anything? If someone would like to very very patiently explain cantor's diagonalization to someone who is very very stupid, then I would greatly appreciate the help

I really hate to ask, but could someone teach me how to solve these? My teacher isn't here and no one in my class is helping me
