Question

What is the distance between `(-3 ,(5 pi)/6 )` and `(5 , (7 pi )/12 )`?

Answer 1

See explanation.

Explanation:

The distance cannot be calculated because the point `(-3,(5pi)/6)` is illegal. Only posssible values for `r` are zero or positive real numbers, there are no limitations for the angle `varphi`
