1. Assume that the problem domain is given by the rectangular domain[a,b][c,d], where [a,b] is the interval on the x-dimension and [c,d] is the interval on the y-dimension and that there are Nx points in the x-dimension and Ny points in the y-dimension. Derive expressions for computing x and y, the grid spacing in the x- and y-dimensions.

Need an expression clearly written.
