After getting your general solution of u(x,y)=ϕ(x+y)+ψ(3x−y). We can notice the following: ϕ(x)+ψ(3x)=sinxϕ′(x)−ψ′(3x)=x. Now we can differentiate our ...

The problem is that the function is not defined when x+y=0 , and to have a limit you must be able to evaluate f(x,y) for all (x,y) sufficiently close to 0 . [If they specify f (x,-x)=0 ...

(The limit on the right-hand side takes the indeterminate form " 0/0 " , so use L'Hopital's Rule, remembering that y is an impicit function of x.) (Evaluate the limit, and use Equation 2.) Since the numerator approaches 1 and the denominator approaches 0 , this limit DOES NOT EXIST.
