Hi there,

I'm having a problem when attempting an implicitplot of an expression containing an integral.

Here is a minimal example of what I'm trying to do:

restart: with(plots): with(DEtools):
f:= t-> t^(-2);
F:= x-> Int(f(t), t=x..1);
G:= (x,y) -> evalf(F(x)-y): G(x,y);
implicitplot(G(x,y), x=0..1, y=0..1);
plots[implicitplot](G(x,y), x=0..1, y=0..1, grid=[100,100]);

The above results in the following error message:
