## Sandy’s Tutor Notes for Spring 2021 📝

During Spring 2021 semester, I worked as a tutor for the School of Engineering. As one of the tutors, we held multiple a series of study sessions every week, on subjects and classes ranging from Calculus I/II/III to Phyics I/II and Chemistry I/II.

I took digital notes on my tablet during every meeting and they have just been fully documented on a separate webpage. I taught Calculus II, Calculus III, and Physics I. It was a lot of fun!

If you are a student and struggling with some of the courses above, you can look at the notes as a bank of problems with detailed solutions. As a tutor or a grader or a teaching assistant, you would be able to find a good source of teaching material and the curriculum of those courses.

## Oracles for Ordinary Differential Equations 🧎♀️

I also worked as a grader for Ordinary Differential Equations course (MATH 220), taught by Professor Van Vleck from the department of Mathematics at University of Kansas. Interestingly enough, one of my responsibilities was also typing up all the weekly homework solutions so that they can be used as "oracles", i.e. "source of truth" when grading students' submissions.

This was quite an experience, because it has been a while since my intro ODE class. In a way, it felt like taking another courseload, as I had to type everything in LaTeX. Solutions are available both in the web form (rendered by MathJax) and in PDF form (rendered with LaTeX). This might be a good source to catch up on your ODEs!

## L’Hôpital’s Rule 🏥

Before I became a tutor at the School of Engineering, as one of the support materials I made for Calculus II was a quick web presentation on L’Hôpital’s Rule, its importance and the motivation behind it.
