Introduction to Differential Equations

**3/23/16**Welcome to Math 20D!**4/14/16**Here is a short worksheet on explanations!**4/18/16**Here are solutions for the practice worksheet on explanations.**4/22/16**Here are solutions for the first midterm.**4/22/16**Here are solutions for the second midterm.**6/2/16**I and the TA's will not hold normal office hours during finals week. Instead, we will hold office hours at the following times: James Dilts: T,W 10am-12pm James Acevedo: T 1-3pm Jonathan Conder: M,T 4-5pm. And to make this very clear, the final exam is Wednesday, June 8th, at 3pm to 6pm in our normal room. If you miss without prior arrangements, you will receive a 0 on the final. It will be approximately twice as long as a midterm, with about half being new material, and half old material. Feel free to bring a (hopefully quiet) snack. Good luck!**6/2/16**Here are some practice problems for the final exam, for power series. Solutions will (hopefully) be posted tomorrow.**6/3/16**Here are (corrected) solutions for the power series worksheet.
