Oct 23 | What kind of analysis do you expect besides analyzing the sourse of error at the boundaries of the function? Also, would you expect a plot of something like in fig 4.1 in the book, or just compare N=10 terms with original function? | The problem asks you to “Discuss the percent error between your series and the function over the given range.” I think that is clear. You are not asked for plots of the series with less than 10 terms, but you might find it educational. |
Dec 16 | For Problem2, part (b), it is stated that B is uniform. Is this B in z direction as well, similar to part (a)? | Yes |
Dec 16 | Please note that Problem 1 is NOT an initial value problem. | |
Dec 16 | Current density is the amount of charge crossing unit area of a surface per unit time. | |
Dec 16 | Problem 2 | There is a sign error in the conductivity tensor. The minus sign on omegaB/nu should be in the (12) component not the (21) component. |
Dec 16 | To solve problem 2(a), is it a valid approach to plug in the tensor relationship into the equation of motion? | No. You need to derive the tensor relationship from the equation of motion. |
Dec 16 | For extra credit, is it asking to show that the electron density stays constant? | Yes |
