Question

What is the distance between the following polar coordinates?: `(1,pi), (-1,pi)`

Answer 1

The answer is 2 units

Explanation:

A circle with radius 1 means this is a unit circle !

Now, `pi` radians is the same as 180 degrees which puts `(1,pi)` at the cartesian coordinate of `(-1,0)`.

Similarly, `(-1,pi)` is at the cartesian coordinate of `(1,0)`.

The distance between these two coordinates is simply 2 units .
