Hello. I've been solving power series problems where the question asks to find 2 power series solutions. I can solve it almost all, I can find the recurrence solution... however while checking the solutions, I see some answer solutions they used c0=1 and c1=0 to find the 2 solutions, and some answer solutions they did not use that. am I missing something? I don't even understand why they used c0=1 c1=0, and when should i use or not.
