## STRAUSS PDE HOMEWORK SOLUTIONS

As the book is not available yet in reserve, here are the homework problems. I plan to put up more practice problems later, so please get started soon. Also look at the hints at the end of the problem , 9. If needed, I will put this on the problem sheet. You may also want to have a look at old homework assignments. Also prove identity 5 on page if you were not in class: Solutions HW problems Ch 9. As the book is not available yet in reserve, here are the homework problems. Th , Th afternoon office hour had to be changed due to some committee rescheduling Some solutions Below we post solutions for some of the homework problems. The material will go until Chapter 4. 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. Solutions HW problems Ch 9.

For each of the following equations, state the order and whether it is nonlinear, linear inhomogeneous i. Solutions HW problems Ch 7. Try first, for a while, even if you do not know right away how to tackle the problem. You are allowed to use up to two cheat sheets. Syllabus We plan to go over most of the material of the first six sections solutiions the book. The TA also made a drop box. If you do not have the book, can also find the problems at the bottom of this web page.

## CHEAT SHEET

If strauuss doubt, ask the TA or me. Or read chapter Solutions HW problems Ch Solutions HW problems Ch 9. Also prove identity 5 on page if you were not in class: Most of the exam problems will be similar to homework or practice exam problems. I also post solutions for the practice midterm.

I am not planning to give the same assignments, but the new ones will likely be similar. We have strausss dropbox in the basement of APM. In order to make it easier for you to print out the assigments, I put the newer assignments homewprk a new page.

While exam problems will certainly not be as long and tricky as some of those problems, it is still useful that you understand how to solve them. If needed, I will put this on the problem sheet.

The material will go over what we have covered from Sections 7 and 9.

I also put a copy on reserve at the science library. We may or may not be able to type solutions for the missing problems in time. Below are some solutions of homework problems, and a practice exam so far only with problems from Section 7. Homework assignments Homework is to be turned in on Fridays unless noted otherwise by 5pm.

Compare this with the causality principle for solutions of the wave equation which implies that information only travels with finite speed c. W, ThProf: ;de assignments Homework is to be turned in on Fridays. 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.
