Question

What is the distance between `(-9 ,( - 3pi)/4 )` and `(-2 ,( 5 pi )/4 )`?

Answer 1

Both `(-3pi)/4 and (5pi)/4` are the same angle (`225^o)` .

Explanation:

Since both coordinates lie on the same vector (with different radii) , the distance between them is simply

distance `=abs(-9-(-2))=7`

Hope that helped
