    You can't, you need to fix a,b,c & d to graph the function. The TI-83 only allows for one unknown, that is x.

    You can enter then into the 'Y=' part just as you have shown in post #3, although you will need fix values for a,b,c, & d.

    Re: sine function

    If your period is 2\pi then maybe its 3\sin2\pi (x + 2) + 4 ? Hard to know without seeing the actual question.

    If you mean you don't know what anthonye means by "complete sine function", then look at post #3 where he explains what he means.
