This is going to seem really stupid, but I've never used Maple before and I just can't figure out what I'm doing wrong. I'm trying to plot a graph of 3 functions (or rather, one function and its first and second derivatives), and it seems like I have the right formula typed but no graph is appearing. This is what I entered:

g0 := x^(2/3)sin(x);

g1 := diff(g0,x);

g2 := diff(g1,x);

p0 := plot(g0, x=0..3, y=0..3):

p1 := plot(g1, x=0..3, y=0..3):

p2 := plot(g2, x=0..3, y=0..3):

display({p0,p1,p2});
