I am attempting to plot a frequency amplitude response for a simple Duffing Problem. I have a range defined for gamma. This means that a, the amplitude is known. The sigma is the frequency of the system. Sigma is a function of the amplitude and gamma. Since gamma is defined as a range the amplitude is known and thus we can find sigma. I plotted the amplitude vs the frequency. I now want to wrap the plot with manipulate so that i can vary the magnitude of the force F, damping parameter c, and the non linearity mue. This is the code i have so far. This plot generates with the slide bars. When i press play however the plot remains static. Please help. Thank You.
