Defining phase in bode plot

[ptc-5430751]

Hi, I have hard time defining and plotting phase in my bode plot. I have managed to plot mag as in attached file. Can anyone suggest how can I approach?

Thank you

You missed passing omega to some of the equations.

I'm not too sure in the results will be what you expected though.

The main fault (missing function argument) was already explained by Mike.

May I additionally suggest to make T a second argument to some of your function to make it easier plotting for different values of T. See at the end of the attached sheet.
