## Welcome to Math 20D (Lecture D, Winter 2022)

This page supplements materials to *``Introduction to Differential Equations''*

Math 20D is a combination of numerical and analytic methods for ordinary differential equations. As such this class involves a valuable amount of practical computations. One may use the materials to further learn about differential equations with many variables (partial differential equations) or even as tools to numerically solve problems from research, industry and applications accross a variety of different subjects.

### Memo to the student:

Remember, this class is here to help succeed in learning the subject.

- •Homework problems will help prepare for Quiz and Final questions
- •Being active in Lecture, Discussion and office hours will help to learn
- •Ask for help when feeling stuck
