Considered to be MATH 126 (see my winter 2016 coursework) on steroids, multivariable calculus was about extending calculus into dimensions higher than two. The course was challenging early on because there was an emphasis on being able to picture surfaces or shapes in three dimensions, and then being able to set the bounds of integration accordingly. Once I got used to thinking in 3-D, the class became much easier. Much of the latter half of the quarter focused on using principles such as the Green's, Stoke's, and divergence theorems to transform difficult integrals into considerably more favorable integrals to solve. I caught onto this quickly, and it was especially insightful to see my instructor, Lucas Van Meter, explain how these theorems were found and why they work. Overall, 324 was a good extension of calculus and made me more confident in being able to expand the principles of calculus into more difficult scenarios and dimensions.
