Better Mistakes Posted April 27, 2023 Posted April 27, 2023 Yeah, i have a masters of science in Psychology. My degree is in English language / literature and I’d never studied psychology before so threw myself in the deep end. Loved every minute of it!

Proof with Euclidean axioms and known theorems that from all quadrilateral figures inscribed in a circle the square has the biggest perimeter. Does there exists a continuous functions that exchanges all irrational points with rational one and all rational points with irrational ones? This type of ****. I thought Math was about solving integrals and limits. Nahh thank you. Probably want to continue Computer Science/Data Science. Irrational numbers are important in electricity and electronics. The vectors are spinning around and drawing circles. I majored in electronics and got that extra math package the other engineers didn't get. The fun begins when the most craziest ideas on math history that didn't have a purpose suddenly matters because of advances in electronics or computer science. I liked learning about how the calculators operate, how can it calculate any sin, cos, tan,... you can throw at it. https://en.wikipedia.org/wiki/Taylor_series

I was taught how to proof all convergence test theorems. However I don't memorize a good chunk of those proofs. Some sure, but not all. Numerical series, functional series, polynomial series and Fourier series. I know how to compute many random series (depending on the level of difficulty). A moderate example would be this: https://math.stackexchange.com/questions/2021790/find-the-maclaurin-series-of-ln-x-sqrtx21?rq=1 The part of (1+x^2)^(-1/2) is a bit tricky though. I prefer analysis over algebra especially abstract algebra. I heard that Calculus was needed to help moon landings. In physics a big problem is being able to find the appropriate function that is needed to evaluate the theorical case. I have no use of it outside of my study fields nor do my computer scientist friends use it in their profession that much. Edited April 29, 2023 by Aristotle
