I also post solutions for the practice midterm. Problem Let u be the solution of Problem 1 of Section 2. I have also added one more practice problem as of Saturday evening. I also put a copy on reserve at the science library. Th , F

There will be a drop box in the basement of the APM building. So instead of 4. As the book is not available yet in reserve, here are the homework problems. We have a dropbox in the basement of APM. Sketch some of the characteristic curves. Also look at the hints at the end of the problem , 9.

I have also added one more practice problem as of Saturday evening. APMoffice hours: ThTh afternoon office hour had to be changed due to some committee rescheduling Some solutions Below we post solutions for some of the homfwork problems.

# MATH – Partial Differential Equations – /16 | CUHK Mathematics

Below are solutions of homework problems from Chapter If in doubt, ask the TA or me. The TA also made a drop box. As the book is not available yet in reserve, here are the homework problems. Even though homework counts for comparatively little for the overall grade, it is extremely important that you do, or, at least, seriously try to do them. You can get from this the full Fourier series for x.

However, I will not expect you to copy lots of specialized formulas such as explicit power series for Bessel functions, explicit spherical harmonics table on pageidentities on pageexplicit formula for Legendre polynomials and associated Legendre functions and normalizing constants on page etc. While exam problems will pxe not be as long and tricky as some of those problems, it is still useful that you understand how to solve them.

We may or may not be able splutions type solutions for the missing problems in time. These are from an earlier course. You may also want to have a look at old homework assignments. Homework assignments Homework is to strausa turned in on Fridays. We have a dropbox in the basement of APM. M, W and by appointment just talk to me after class or send me an email.

Also look straiss the hints at the end of the problem9. W, ThProf: There will be a drop box in the basement of the APM building. Please click below for new assignments:. Problem Let u be the solution of Problem 1 of Section 2. For each of the following equations, state the order and whether it is nonlinear, linear inhomogeneous i.

MondayTuesday solutios The problems in the midterm will be similar to homework problems or practice exam problems. Below are some solutions of homework problems, and a practice exam so far only with problems from Section 7.

If needed, I will put this on the problem sheet. I also post solutions for the practice midterm. Solutions HW problems Ch I also put a copy on reserve at the science library. Also prove identity 5 on page if you were not in class: Otherwise, these exercises and solutions do not really help you!

Compare this with the causality principle for solutions of the wave equation which implies that information only travels with finite speed c. Solutions HW problems Ch 9.

## Math 3435 PDE

I am not planning to give the same assignments, but the new ones will likely be similar. Most of the exam problems will be similar to homework or practice exam problems. I have posted an old midterm and more relevant problems below.
