Does anybody know of a list/diagram showing how various math subjects lead to other subjects and their interactions? So like Algebra -> Calculus 1 -> Differential Equations, Calculus 2 -> etc.?
I'm trying to build a solid foundation to get to advanced courses/topics like Real Analysis, Wave Propagation, Numerical Methods, etc. and would appreciate figuring out what's important to know for different topics. Thank you!
You could try asking https://academia.stackexchange.com/.
But usually, it's
Basic Math -> Pre-Algebra -> Algebra -> Geometry -> Trigonometry (grade 9 ish) -> precalculus (grade 11) -> calculus (grade 12) -> differential calculus (derivatives and such) (post secondary) -> integral calculus (integrations and such) -> multivariable calculus (with many variables) -> differential equations (this comes far, its not easy) -> linear algebra (not really last but its best learned later on since you won't see the use of it before)
After this, you are open to basically anything.
