Unformatted text preview: y + 2 xy + y = 0 . (1) a . (8) Find a recursion relation expressing a n +2 in terms o a n or all n 0. b . (2) Express a 2 , a 4 and a 6 in terms o a and express a 3 and a 5 in terms o a 1 . (Remark: In this way one can express the general solution o the diferential equation in the orm y = a y + a 1 y 1 where y is the sum o a power series with only even powers o x , and y 1 has only odd powers. But you do not need to do this now.) 1...
