i have used series solutions to differential equations many times but i never really stopped to think why it works i understand that the series solution approximates the solution at a local provided there is no singularity in which frobenius is used but i am not understanding how exactly it works because the series is only valid for local value of x then what is the use of using such a solution and more specifically how is this justified when using it to solve Legendre differential equation is it because we are only interested in the behavior of solution form -1 to 1
thanks for the help
