There was a slight error in the term test review sheet which has been corrected (involving the factor multiplying the z in the sinh and cosh terms in the last series expansion on the first page).

Also, for the test tomorrow I do also expect you to remember that P_l(x) is an even function if l is even, and is odd if l is odd, and also that P_l(1) = 1. This means, in particular, that P_l(0) = 0 when l is odd (you don't need to memorise the expression for P_l(0) when l is even), and that P_l(-1) = (-1)^l.

Finally, I want to emphasise one more time that the test is on Wednesday and will begin at 7.00, NOT 7.10. You should be there early (ideally by 6.50). If you come at 7.10 you will NOT be allowed to make up the missed time! You will not be allowed to enter after 7.45 (or leave before 7.45).

Let me know if you have any questions, and best wishes with the test!
