  1. this is what even i think how can you split 45 into two equal parts...P.S- he noted that we cant use 9 as 6...
  2. Correct. Good job. I wonder if there is a proof of this that is not overly complex? Edit: Well, No. I just found the proof, and it's not beautiful for its simplicity. You start with the Law of Sines, and 2 1/2 pages later you have a symmetrical expression for one side. "Do not try this at home." oh i am so sorry .....i mistook it for the eulers line....my bad...
  3. complete the following series ...it is a bit harder than the previous ones... 11, 12, 13, 14, 15, 16, 17, 20, 22, 24, ? , 100, 121, ?
  4. use spoiler !!the little button in the post box that says "s"!!
  5. 228^251 * 126^23416 * 37^217 * 213^19. what will be the last digit of the resulting Answer?
  6. Two consecutive numbers are given to A and B. when A is asked ‘do you know B’s number?’ A denies. when B is asked whether he knows A’s no., B also denies. at the very moment, A replies that he knows B’s number. what may be B’s number?
  7. Which term will be the next term in the series? 18, 46, 94, 63, 52, ?
  8. even i am having the same confusion...
  9. It seems like this problem is dependent upon what is a reasonable a priori distribution for N. OMG!you are one hell of a methematician...lol
  10. You're right about the bisector case. But for the trisector case there is more than one point. In fact there are three places where a trisector of one angle first intersects a trisector of one of the other angles. And there is something special about those three points.
  11. Use three 9's and arrange them using the mathematical signs to form the number one.
  12. didnt your first image touch only one coin.??/
  13. Do we have to name that point?
  14. hey man can you tell me how you worked out that the angle between alpha and beta should be 120 degrees .i just acant understand..Thanks I knew someone would ask that question It was a little messy and maybe not in the most efficient way, but... thanks!
