Using a slider to control a plot.

I have a project that we have to plot Sinusoids. I already figured out how to add the Amp and Freq from user input in GUI, but I'm suppose to use a slider to move the sin, acting as a phase shift between -2pi to 2pi. I am completing stomped. Thank you for any help you could give.
