The discussion centers on the optimal sequence for taking multivariable calculus, linear algebra, and differential equations. Many participants advocate for taking linear algebra before or concurrently with multivariable calculus, as it provides foundational concepts that enhance understanding in calculus. Some suggest that differential equations should follow linear algebra due to the significant overlap in concepts. There are varying opinions on whether to take these courses simultaneously; while some have managed to do so, they report challenges in grasping the material fully. The order of courses may differ based on the major, with physics majors often benefiting from a specific sequence: multivariable calculus, linear algebra, and then differential equations. Additionally, some participants note that the math required for general physics courses is minimal, suggesting that the timing of these math courses may not heavily impact physics studies. Overall, while there are personal preferences and institutional prerequisites, linear algebra is frequently highlighted as a crucial course to take early in the sequence.
