I tutor first and second year university students, typically with their physics coursework. This semester I have been asked to also teach/tutor calculus 2 & 3 (integral & multivariable). It's been quite a few years since I took these courses so I was hoping to find a text that would work as a refresher on the topics -- especially one that takes a novel approach to teaching the subject for my own pedagogical benefit. I was curious if there was something analogous to Needham's 'Visual Complex Analysis' for calculus.
Thank you.
