36 Methods of Proof 1 Proof by obviousness “The proof is so clear that it need not be mentioned.” 2 Proof by general agreement “All in favor?…” 3 Proof by imagination “Well, we’ll pretend it’s true…” 4 Proof by convenience “It would be very nice if it were true, so…” […]

We interpolate points by polynomial $latex P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j} $ Its coefficients are found as a solution of system of linear equations: $latex \left\{ P_{N-1}(x_k) = f_k\right\},\quad k=-\frac{N-1}{2},\dots,\frac{N-1}{2} $ Code example: def fib(n): if n == 0: return 0 elif n == 1: return 1 else: return fib(n-1) + fib(n-2)
