Mark asks…PHysics help, help please?2. Chapter 1, Problem 40. Given points (r1, 1) and (r2, 2) in polar coordinates, obtain a general
formula for the distance between them. Simplify it as much as possible using the identity
cos2 + sin2 = 1. Hints: Draw a diagram (see Figure 1.5). Write the expressions for the two points
in Cartesian coordinates and substitute into the usual distance formula.
That is supposed to be cos squared theta and sin squared thetaNancy answers:The
