See AnswerQ: Two points in a rectangular coordinate system have the coordinates (5
Two points in a rectangular coordinate system have the coordinates (5.0, 3.0) and (23.0, 4.0), where the units are centimeters. Determine the distance between these points.
See AnswerQ: Two points are given in polar coordinates by (r, θ
Two points are given in polar coordinates by (r, θ) = (2.00 m, 50.0°) and (r, θ) = (5.00 m, -50.0°), respectively. What is the distance between them?
See AnswerQ: Given points (r1, θ 1) and (r2,
Given points (r1, θ 1) and (r2, θ 2) in polar coordinates, obtain a general formula for the distance between them. Simplify it as much as possible using the identity cos2 θ + sin2 θ = 1.
