Question: Plotting the Amplitude vs the External Driving Frequency

April 15 2014 coldnut 5


I am trying to make a plot that shows the amplitude of a second order linear system relative to an external driving frequency ω, but I am having trouble defining my function. Here's what I have so far.



When I pass the amp function ω=0 and F=4, I don't get back what I expect. I would think that those symbols should evaluate to the values I passed in. I have tried different parameter names etc..


All I am trying to do is plot the function shown above for F=4 and 0≤ω≤5. I know I could manually plug the values in, but I thought I'd ask the proper way to do it. Any help is greatly appreciated. Thanks folks!
