Re: more than 1 function with Plot3D227 (9/15/2004 6:03:37 AM) comp.soft-sys.math.mathematica Hi Ron,
are your equations correct?
60 = 2*x2 + x2 => x2=20
hence:
20 = 2*x1 + 20 => x1=0
???

this might get you started:
f[x_] = x^2
d[x_] = D[f[x], x]
Plot[{f[x], d[x]}, {x, -3, 3}]

try this example please:
a = 3
b = 5
v = 7
llimit = v/(Pi*b^2)
Plot3D[Sin[l*r], {r, a, b},
{l, 0, llimit}]
As r cannot exceed b you can replace r^2 by b^2 in llimit.

what about
