partial derivations on axis

Write a function that computes the partial derivations of a given image. Write code for (a) Forward derivation in x-direction, (b) Backward derivation in x-direction, (c) Forward derivation in y-direction and (d) Backward derivation in y-direction. I don't understand the difference between First order derivations, Second order derivation, partial derivations and Forward and Backward derivation in an axis.

You should probably know to calculate partial derivatives which is one dimensional(meaning moving along a certain direction). Make use of symbolic toolbox as your tool to compute each and then plot them to see the direction.
