variables.
Answer all the questions. Show all your own and personalized workings, you get ZERO
to a question if we see that you have copied someone’s else solution word by word.
If you choose to submit via myUnisa, note that only PDF files will be accepted.
Note that all the questions will be marked therefore, it is highly recommended to attempt all of them.
Question 1
1. Find the radius and interval of convergence of the following series:
X∞ (−1) n−1 x 2n−1
n=1
(2n − 1)!
2. Rewrite the expression below as a single power series:
X∞ X∞
cn+1 x n−2 − 4cn x n−1 .
n=2 n=1
3. Use the power series method to solve the initialvalue problem
00 0
(x + 1)y − (2 − x)y + y = 0, y(0) = 2, y0(0) = −1;
where c0 and c1 are given by the initial conditions.
4. Use the power series methodPto solve the initialvalue problem.In particular, find c 0, c1 , c2, c3
and c4 in the equation y(x) = ∞n=0 cn x n .
y00− x 2y = 0; y(0) = 3, y0(0) = 7.
Question 2
Using the method of separation of variables, find a solution for the following PDEs:
