Sets and Logic MHF3202 4628 Class-C Prof. JLF King 07Feb2008 C1: Show no work. Write DNE ( for “ Does Not Exist ) in a blank if the indicated operation cannot be per- formed, or if the described object does not exist. Use V () for the Vince invariant of a cell in a TicTacToe board. Use TTT to abbreviate “TicTacToe”. a The author of our text is ± ² ³ ´ Circle : Archimedes Cantor DNE Euler Devlin Machen b In Qubic , V ( Center cell )= ....... . And V ( Edge cell )= ....... . There are ....... many cells whose Vince-invariant equals V ( Edge cell ). c The 7 × 7 TTT board has .... many TicTacToes. And 4 × 4 × 4 ( Qubic ) has .......... many TicTacToes. d An explicit bijection f : N , ± Z is If n is even , then f ( n ) := .......................... . If n is odd , then f ( n ) := ........................... . e An explicit bijection g : ( π 2 , π 2 ) , ± R is g ( x ) := ........................................... . f LBolt: Gcd(70 , 42)= ....... · 70 + ....... · 42. So (use LBolt twice) G := Gcd(70 , 42 , 30)= ...... and ........ · 70 + ........ · 42 + ........ · 30 = G .
