WebWhen we know a point in Polar Coordinates (r, θ), and we want it in Cartesian Coordinates (x,y) we solve a right triangle with a known long side and angle: Example: What is (13, 22.6°) in Cartesian Coordinates? Use the Cosine Function for x: cos( 22.6° ) … WebA radian is the measure of an angle θ that, when drawn as a central angle, subtends an arc whose length equals the length of the radius of the circle. When radius r = arc length r, the angle θ measures 1 radian. (Thus the naming of "radian" with its connection to "radius".) Radian measure is another way of expressing the measure (size) of an ...
