Additionally, what topics from that same course are relevant to probability? I ask because I'm afraid I might forget some of the topics from my calculus series after one semester of disuse. I mean, I know I should probably brush up on my calculus skills in preparation for any math class that uses it, but it would be nice to have a good idea of what in particular I should study for these courses: Partial Differential Equations I Integral surfaces and characteristics of first and second order partial differential equations. Applications to the equations of mathematical physics. Pre: Calculus III, or consent. Recommended: Calculus IV and Intro to ODEs. Probability Probability spaces, random variables, distributions, expectations, moment-generating and characteristic functions, limit theorems. Continuous probability emphasized. Pre: Calculus IV (or concurrent). Any insight on what calculus topics that are relevant to these classes will be much appreciated.
