MTH 172 Lecture Notes - Lecture 28: Cartesian Coordinate System, Polar Coordinate System
Document Summary
Provide a generalization to each of the key terms listed in this section. A pole is a point in the polar coordinate system. A polar axis is a ray with a vertex at the pole in the polar coordinate system. Polar coordinates are ordered pairs in the form of (r, ). (r, ) Any point with (r, ) as their respected polar coordinates, which has in radians, can represent by either (r, + 2 k) or even ( r, + + 2pik), which notes that k is any integer. On the other hand, (r, ) are also the poles polar coordinates, which notes that being any possible angle. Polar coordinates are ordered pairs in the form of (x, y). Rectangular coordinates = p olar/cartesian coordinates (x, y) = (r, ) x = r cos y = r sin . Find the distance, which is r, from the origin to the given point.
