## Main Question or Discussion Point

I need to draw two graphs in the same axis in matlab, and I'm novice in matlab, so if someone can type the code for this it will be much appreciated, this is the only way I can learn right now.

the graphs are of:

[tex]\frac{1}{2}m\omega^2A^2e^{-\gamma t}[1+\frac{\gamma}{2\omega}sin(2(\omega t+\phi)+\frac{\gamma^2}{2\omega}cos^2(\omega t+ \phi)][/tex]

and [tex]\frac{1}{2}m\omega^2A^2e^{-\gamma t}[/tex]

where A,m and gamma are arbitrary parameters, and [tex]\omega_0/\gamma=10[/tex]

and [tex]\omega=\sqrt{\omega_0^2-1/4\gamma^2}[/tex]

I need that the graph will span over a number of periods.

As I said I'm novice and not sure how to handle this, and reading the help may take more time for me.

thanks in advance.
