Step 1
We assume that the solution can be written as a power series: Y(x) = ∑(n=0 to ∞) an x^n We substitute this into the differential equation and equate coefficients of like powers of x: Y" - 2xy + 8y = 0 ∑(n=2 to ∞) n(n-1)an x^(n-2) - 2x ∑(n=0 to ∞) an x^n + 8 Show more…

The recurrence relation for the power series solution about x = 0 of the differential equation y'' + (2-4x^2)y' - 8xy = 0 is (for k = 0, 1, 2, ...)
Solve the differential equation y'' + 4y =0 using the power series method.
