Formulas for sinusoidal curves.

Assume that the image represents a perfect sinusoidal curve with points indicating exact maxima, minima or "equilibria" (i.e., inflection points or "middle points"). Fill in the crude little boxes with your answers. (Fill each box, even if they are things you would not ordinarily write, such as 0's and 1's, otherwise an error will be generated.)
Write an equation that corresponds to the graph below. (You'll have to write "Pi" or "pi" for the symbol Created by webMathematica.)
