What does the derivative of a function at a point describe?

WebI understand that the derivative of a function f at a point x = x 0 is defined as the limit f ′ ( x 0) = lim Δ x → 0 f ( x 0 + Δ x) − f ( x 0) Δ x where Δ x is a small change in the argument x … Webgrid. Since we then have to evaluate derivatives at the grid points, we need to be able to come up with methods for approximating the derivatives at these points, and again, this will typically be done using only values that are deﬁned on a lattice. The underlying function itself (which in this cased is the solution of the equation) is unknown. pope francis changes feast of st martha
