 Apr 1 comment Interpret the equation $17+28y+4x^2+4y^2=8x$ geometrically +1: Good derivation Apr 1 answered Interpret the equation $17+28y+4x^2+4y^2=8x$ geometrically Mar 21 awarded Citizen Patrol Mar 13 revised Birthday paradox: Comparing the original version with the same-birthday-as-you version added 221 characters in body Mar 13 accepted Birthday paradox: Comparing the original version with the same-birthday-as-you version Mar 12 comment Birthday paradox: Comparing the original version with the same-birthday-as-you version Ok, I begin to see the idea. I think this comment is rather helpful, perhaps you want to include it into your original answer. Thank you again. Mar 12 comment Birthday paradox: Comparing the original version with the same-birthday-as-you version Thank you for your answer. I agree both are similar, yet in the case of the original paradox the falling factorial power in the numerator is growing considerable slower than $364$ to the $n$ in the other version. This is why you need $23$ in one case and $253$ in the other after all.

Mar 7 comment How to prove that the limit is max(0,x)? How do we see that the result in the first case is not valid for x<0? Mar 7 asked How to prove that the limit is max(0,x)? Mar 7 comment Is there an analytic approximation to the minimum function? I think it is off by $\frac{log 2}{k}$ when equal.
