Here is a graph of the equation
A graph. Horizontal axis, theta, scale negative 2 pi to pi by pi over 2. Vertical axis, y, scale negative 5 to 1. The curve passes through the points negative 3 pi over 2 comma negative 1, negative pi comma negative 3, negative pi over 2 comma negative 5, 0 comma negative 3, pi over 2 comma negative 1, pi comma negative 3, 3 pi over 2 comma negative 5.

Explain why the tangent of
A circle with center at the origin of an x y plane with grid. The circle has a diameter of 4 units. The point P lies on the outside of the circle, in the first quadrant, and is closer to the y axis than the x axis. Point Q lies on the outside of the circle, in the third quadrant, and is closer to the y axis than the x axis. A line passes through points P and Q.
