I have a function of two variables, f[x, y], which when evaluated for values of
x=y results in:
1
Power::infy: Infinite expression -- encountered.
0.
As there is an (x-y) term in the denominator of the function. However,
the Limit[f[x,y], x-y] does exist, and evaluates to a finite number.
The question is, how do I construct a rule that conditionally evaluates
the limit of f[x,y] rather than f[x,y] whenever x=y?
