How to solve recursive equations
WebDefine A ( z) = ∑ n ≥ 0 a n z n. Rewrite your recurrence without subtractions in indices: a n + 2 = − 4 a n + 1 − 4 a n. Multiply by z n, add over n ≥ 0, and recognize the resulting sums: A ( z) − a 0 − a 1 z z 2 = − 4 A ( z) − a 0 z − 4 A ( z) By running the recurrence backwards, you have a 0 = − 1, and: A ( z) = 2 ( 1 ...

WebOct 2, 2012 · You will need to specify F ( 0, r) and F ( s, 0) as initial conditions. Your recurrence is precisely that for Pascal's triangle. If you specify F ( 0, r) = F ( s, 0) = 1 you will have F ( n, m) = ( n + m n). You can use linearity to turn it into a sum over initial conditions and binomial coefficients.

Web4 Answers Sorted by: 1 Let f ( x) = ∑ n = 0 ∞ a n + 1 n! x n. The conditions on f are f ( 0) = − 2, f ′ ( 0) = 12, and 4 f + 4 f ′ + f ″ = 0. Solving this IVP gives f ( x) = e − 2 x ( 8 x − 2). The n -th … WebYes, when using the recursive form we have to find the value of the previous term before we find the value of the term we want to find. For example, if we want to find the value of term 4 we must find the value of term 3 and 2. We are already given the value of the first term.
