Coverage of the final exam
*************************
Hello Professor Taylor
I have a question regarding the final exam on May 5. Is it a cumulative exam? Or just the sections covered after Test 2? Can you please tell me what all sections to focus on?
Thank You,
###########
**************************
The final exam will be comprehensive, however the material covered since midterm#2 will receive more detailed emphasis.

webwork questions
***************
1) (section 8.2 #3) Hello,
I was trying to solve the problem, but I am having issues trying to reach
the quadratic formula form.
In the book, it outlines a way using theorem 1, but it does not explain how
to find it.
I've found -2 = a1 + a2 from C = a1(r1)^0 + a2(r1)^0, and -4 = a1 + a2 from
C = a1(r1)^0 + a2(r1)^0, but I am stuck on how to approach the problem
next.Thanks,
2) number 8.2 problem 4 is completely unsolveable with the r that webwork
claims is correct. please help me!
********************
1) Interestingly, problem 4, which is copied above describes pretty carefully how to do this, except that you would change the right hand side to 9r^{n-2} instead of -4r^{n-1}-4r^{n-2}. Also, since -4 is the initial condition corresponding to n=1, so you would need the equation -4 = a_1r_1 + a_2r_2 instead of -4 = a1 + a2; it's important for you to understand this, because the final exam will be an unhappy experience otherwise!
2) I'm a little confused by what you mean by "completely unsolvable", the problem basically takes you by the hand and leads you to the solution, which it looks like you've found. Please clarify.
