Скачать или смотреть Polar Coordinates: Example 4: Circle

In this video I go over another example on polar coordinates and this time look at graphing the curve r = 2. This curve is every point r and θ in which r = 2. Since r is just the distance from the Origin or Pole, this means that we in fact have a circle with radius 2. This is because the distance is always 2 for all values of θ, which is just the angle that is being rotated. In general, the equation r = a is a circle with radius |a| or absolute value of a. This example illustrates the simplicity of describing circular equations using polar coordinates, in which a constant represents a circle. This is analogous to a straight horizontal line in Cartesian coordinates, such as y = 2 for example. This is a great video to understand the ease in which we can represent circles through the polar coordinate system, so make sure to watch this video!
