You will learn how to convert from polar coordinates to rectangular coordinates (or Cartesian coordinates or coordinates in a Cartesian plane), and vice versa in this lesson. First, Professor Berger gives you an overview of polar and rectangular coordinates. Then, you will learn how to convert a polar cordinate (r, Theta) into a rectangular coordinate (x, y), using the equations x = rcosTheta and y = rsinTheta. To convert from rectangular to polar, you will use the equations r = root(x^2 + y^2) and Theta = arctan (y/x). To illustrate the use of all of these formulae, Professor Burger will walk you through the conversion of (3, pi/6) from polar to rectangular coordinates and the conversion of (-1.1) in rectangular coordinates to equivalent polar coordinates. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.
