Find the set of all points of continuity for:
i know that the domain is whenever ln is positive, so its whenever x-y>0 , x>y
is it continuous on all points of the domain?
also is it considered continuous on the edges of the surface?
thanks

f(x) is said to be continuous when lim(x->a+)f(x)=lim(x->a-)f(X)=f(a).
where a is any point in the domain.
following a similar analogy for your 2 variable function i think f(x,y)is continuous everywhere as f(a,a)=0=lim(x->a+-)lim(y->a+-)f(x,y) in the domain which means that all the points of continuity will lie in the
domain. and the domain is given by whenever x>y for all reals.
