Implicit equation's graph f:=f(x,y)=0

By now Mathcad wasnt able to represent graphics of implicit functions.

Lets say being f:=x^2+sinx+x*y=0

For upper case Mathcad isnt able to represent the graphic of the plane curve x^2+sinx+x*y=0 or other example for a 3D surface z^2+4*x^2+sinx+x*y=0

Mathcad want just explicit expression like z:=x^2+x*y to be able to represent or z:=z(x,y), but we know that majority of expressions are implicit like f(x,y)=0 or f(x,y,z)=0 that are most general

Would be great if Mathcad solve this thing

Mathcad does all that, simple, quick. There are many examples in the qs.

Visit the Mathcad usage since june 20, download all my work sheets .
