    You are looking for three numbers a\sin(bx)+c to do that.

    Hint: \frac{-\pi}{2} is one of them.

    Re: Sine Graph Equation

    I am pretty sure c is 1, but how do I find a or b?

    Take a graphing calculator and try some possibilities.

    You say c=1 and I told you that -\frac{\pi}{2} is one other answer.
