Alyanna Lopez ANAGEOM EK Polar coordinates is defined as pair of coordinates locating the position of a point in a plane, the first being the length of the straight line (r) connecting the point of reference to the particular point you are locating and second being the angle (θ). It is another way of locating points along a plane using radius (r) and theta (θ) instead of using coordinates x and y. One practical application of the polar coordinates is studying the motions of the human body. This is because the human body utilizes pivotal joint movements. In learning about the topic of polar coordinates, I thought about some applications of which it would be useful. Through watching lots of movies like Battle Ship, Transformers, and a lot more sci-fi movies; I saw a lot of radars and mapping devices that seems to run in the polar coordinate system. Using this mathematical model, bodies that are moving in within a central axis or orbiting in a central point works on a polar coordinate system. Polar coordinates are important and are useful in the following applications that this would be discussing. One practical application of the polar coordinates is studying the motions of the human body. This is because the human body utilizes pivotal joint movements and since pivotal movements progresses circularly it can be mapped using polar coordinates. Polar coordinates can also be used in navigation devices as the destination or direction of travel can be given as an angle and distance from the object being considered. These navigation devices are commonly used by the military, the navy, and air force. A concrete example would be an aircraft that uses slightly modified polar coordinates for navigation. Also, radial symmetry provides natural settings for the polar coordinate system, with the central point acting on the pole. A concrete example of this theory is the groundwater flow equation when applied to radically symmetric wells. Systems with a radial force are
