comment what is the parametric form for “mystery curve”?
@A.P. : Thank you, I am going to need some time to comprehend what you are saying.

@A.P. : I seriously cant see how this is same as parametric form without opening it up using Euler's identity. This formula doesn't explain the periodicity of the curve. If indeed it has a periodicity at all.

@A.P. : sorry I am a bit rusty, did polar form come in form of $r=f(\theta$)? If yes then I think it is a bit messier than this (imho)

comment Example of a convergent series for which integral test fails?
@K.Dutta : so in theory at least the integral test is the ultimate test.

comment Example of a convergent series for which integral test fails?
@John : so why use the other tests when integral test is enough?

comment Average distance between 2 points on surface of sphere?
@achillehui : just a curiosity , is there a generalisation that generalises geodesic distance to n dimensions?

comment Average distance between 2 points on surface of sphere?
@CameronWilliams : How can I generalise that to spheres of n dimesion? That is the motivation for asking this question.

@PrasunBiswas : that specific result or a more general form that makes that as a specific value?

@PrasunBiswas : yes I agree nothing can be that general, is there even a taxonomy of identies or the their generating families exist?
