WebFinite Difference Approximating Derivatives. The derivative f ′ (x) of a function f(x) at the point x = a is defined as: f ′ (a) = lim x → af(x) − f(a) x − a. The derivative at x = a is the slope at this point. In finite difference approximations of this slope, we can use values of the function in the neighborhood of the point x = a ...

Finite difference is often used as an approximation of the derivative, typically in numerical differentiation. The derivative of a function f at a point x is defined by the limit. If h has a fixed (non-zero) value instead of approaching zero, then the right-hand side of the above equation would be written
