Homework Statement
solve the DE using power series about x_0 = 0
y'' + xy' + 2y = 0
so, i want a solution in form of y = [sum from n=0 to n=infinity]c_n x^n
(i hope this makes sense, i don't know how to get summation symbol)
y = [sum from n=0 to n=infinity]c_n x^n
y' = [sum from n=0 to n=infinity]nc_n x^(n-1)
y'' = [sum from n=0 to n=infinity](n-1)n c_n x^(n-2)
then plug these values into DE..
i just need to know if i am correct so far..then i will proceed..thanks
