1. Find the solution to the differential equation using a power series about 10 = 0. Find the recursion relation and find the first four terms in each of the two linearly independent solutions (unless the series terminates sooner.) Your final answer should be the general solution. (a) y" zy+2y=0 (b) (1+r²)y" -4xy' +6y=0 (c) (1-x)y"+ry'-y=0
