comment What is your favorite application of the Pigeonhole Principle?
@DanielV: not assuming, estimating. i think maximum number of hair possible on a human body is even less than number of people in new York.

comment Does the Law of Sines and the Law of Cosines apply to all triangles?
@Sourisse : yes you are absolutely right, so I'll mention it :) That it holds Only for triangles in Euclidean geometry. They are not always true for triangles on the surface of sphere for example.

comment Ternary equivalence relations that are not equivalent to some binary equivalance
Thank you @AndréNicolas, yes, either and both. at this stage I take either. Is there a theorem that expresses whether any n-ary relation can be decomposed into n-1 ary relations? or how ? Then I will chase that one instead of this question

comment what is the parametric form for “mystery curve”?
@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.

comment what is the parametric form for “mystery curve”?
@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?
