In a radio wave the trig function for low c would be y=a sin(32πx). Where 32π is the frequency and a is the amplitude. The frequency is how many cycles it has in one second and amplitude it the range it has allowing for different volumes.
The online graphing calculator you used had a flaw to it. I do not know if the calculator is just not fine tuned enought to do a function like y = sin32pix, or what... Consider your notes on frequency and how you calculate it. Given your equation, how many cycles/periods should occur within 1 second? I would change the scale on your online graphing calculator and see if that makes a difference.
