Hi Guys,

Today i need to understand the mathematical equation.

Below attached equation is the first derivative of 2D function, f(x+u, y+v) by the taylor series.

The Taylor series to the first order of f(x,y) at the point (a,b) is

If you replace (x,y) by (x+u,y+v) and (a,b) by (x,y), you are done.
