What is the distance between the following polar coordinates?: # (7,(3pi)/4), (3,(pi)/8) #
You can use the Law of Cosines.
If you plot the polar coordinates and draw lines from the origin to the points, you will have 2 sides of a triangle. The 3rd side will be the distance between the 2 points.
Find the angle
You can also solve this problem by converting the polar coordinates to rectangular coordinates and using the distance formula.
