```
So I am plotting an implicit function the that has small y values(0
to .5) and large x values(0 to 74).
the graph i get is not readable and i can 't resize it using the edges
it is lame.
So does anyone know how to rescale the the implicit plot so that i
could read it. I have included my code, below. I am using Mathematica
5.2

-----------------------------------------------------------------------------

\!\(<< Graphics`ImplicitPlot`\[IndentingNewLine]
\(u0 = 76;\)\n
\(\[Omega] = \[Pi]/12;\)\[IndentingNewLine]
\(uh = u0*\[ExponentialE]^\((\(-k\)*t)\);\)\[IndentingNewLine]
\(up = 7\ \((5 -
5\ \[ExponentialE]\^\(\(-k\)\ t\) - \(1\/\(k\^2 + \[Omega]
\^2\)\) \
\((2\ \[ExponentialE]\^\(\(-k\)\ t\)\ k\ \((\(-k\)\ Cos[
3\ \[Omega]] + \[Omega]\ Sin[
3\ \[Omega]] + \[ExponentialE]\^\(k\ t\)\ \
((k\ \
Cos[\((\(-3\) + t)\)\ \[Omega]] + \[Omega]\ Sin[\((\(-3\) +
t)\)\ \[Omega]])\))\))\))\);\)\
\[IndentingNewLine]
\(myANS = uh + up;\)\[IndentingNewLine]
\(U = myANS\ ;\)\n
ImplicitPlot[U == 30, {t, 0, 72}, {k, 0.2, 0.48}]\n
Plot3D[U, {t, 0, 72}, {k, 0.2, 0.48}]\)
