Derivatives of functions are computed using differential calculus. A derivative in calculus is defined as “the rate of change of quantity y with respect to quantity x”. This sounds very similar to the ...

A non-linear function So we saw previously that the derivative is the rate of change of our function. We express this as $ f' (x) = \frac {\Delta f} {\Delta x}$. So far we have only calculated the ...

smooth functions and in their derivatives. The method is constructed from a local stencil of grid point values and is based on a polynomial annihilation technique. By varying the order of the method ...
