Question: function as a parameter in a procedure

Hi there,

I am doing an exercise which asked me to perform a taylor expansion for an arbitrary function of 2 variables (x,y) around an arbitrary point (x0,y0). Here's what I've got:

In the above,s and u are any 2 functions of interest.x0 and y0 are the coordinates of the point of expansion.I guess there was something wrong with s and u.What should I type in,in order to make any bi-variate functions as parameters in my procedure?

Please Wait...
