Find the equation represented by the given graph.

A graphic of a Cartesian plane with vertical axis Y and horizontal axis X is shown. The Y axis has labels at negative five and positive five, with notches at all the integers in-between. The X axis has labels at pi over two, pi, three pi over two, and two pi. A smooth curve begins at four on the Y axis, travels down through pi over two on the X axis, continues traveling down to a minimum point the same distance below the axis as the beginning point was above the axis, then travels back up through three pi over two on the X axis, up to a high point above two pi (the same height as the initial point).
