Question about CAS and Graphing

plotfun() sound like plotting a function f:=int(x,x) is called an expression right? If I define f(x):=int(x,x) i.e. a function there is no graph. Yes plot(f(x)) works fine, but you should keep in mind that students not present in forums should find an intuitive way to use the tool.

Your function is not well defined. No matter what cas you use f(x):=int(x,x) does not appear to be well defined. Is f(3) to be 1/2*3^2 or int(3,3)? The plotfunc command requires an expression representing the function as an input and not an actual function object itself.

And yes I agree -- this is merely a workaround.
