hey all im taking a graduate level fluid mechanics course. we are using a good amount of vector calculus (expected) and also tensor algebra, leading into the kronecker delta and Levi-Civita symbol (shockingly never saw these before, though implicitly used them). it seems linear algebra is being introduced. for those of you who have studied far in the field, how much math is required for masters and phd level courses? i only ask because my undergrad is math, where i covered linear algebra, pde's, and vector calculus; am i missing anything or do i have the basic "tool kit" that advanced coursework in fluids requires? thanks!
