13) An air traffic controller's radar display uses polar coordinates. A passing plane is detected at ° counter-clockwise from north at a distance of miles from the radar. Thirty seconds later the plane is detected at ° and miles. Estimate the plane's speed in miles per hour.

However, the same point P can be located by using polar coordinates r,θ where r is the distance of P from the origin and θ is the angle, measured anti-clockwise, that the line OP makes when measured from the positive x-direction.
Any point P can be described by the coordinates ( , ), where is the radial distance from the point to the origin (also referred to as the pole) and is the angle subtended by the radial line connecting the point to the origin and the x-axis. Note that the axis is often called the initial line. = sin2 .
