>>11656170Got frustrated that I was heading for a dead end in my IT job even though I was making good money and that I wasn't great at math. I studied calc II, Calc III, Vector Calc (div grad curl) over summer of first year of this process, brushing up on PreCalc and Trig along the way. Linear Algebra and Differential Equations in the fall. Introductory discreet mathematics in the winter, followed by numerical analysis and Linear Algebra in the spring (proof based, Friedberg, covered neat stuff like Dual Spaces and JCF) Completed mechanics and E&M sequence this year as well. Throughout this I covered some assorted topics in enumerative combinatorics (wrote back and forth a researcher at a local uni) Fall I studied cryptography (silverman), algebra (judson, free and online, great book for beginners), probability and stochastic process (terrible book, don't recommend) and elliptic curves (silverman rational points on elliptic curves). Winter was Rings / Fields, more cryptography (pairings, lattices, curves), Algebraic Coding Theory and Number Theory (basic stuff like CRT, sum of squares, reciprocity, multiplicative number theory, Ireland and Rosen is my go-to book) This quarter I've been doing introduction to analysis in single variable, intro topology (my weakest fields), Galois Theory and more Number Theory (algebraic number theory, continued fractions, approximation, some neat stuff in finite fields) I completed GE requirements at community college and studied some of these courses there as a official classes so I could get credit. I am in California so I transferred from there.
