Guest arunhallan Posted April 17, 2003 Report Share Posted April 17, 2003 Could someone solve these for me please? 1. Solve the congruence: 72x = 2 mod 245 and 2. COnsider the matrix: A = (1 3) (4 5) Find the matrix M such that M(to the minus 1) AM is diagonal Hence find a formula for A (to the n) I have a whole paper i need the answer to in .pdf form if anyone would be willing to solve for me??

Guest Palindrome Posted April 17, 2003 Report Share Posted April 17, 2003 Isn't that extreme and bare-faced cheating? Link to comment Share on other sites More sharing options...

Guest Emad Posted April 17, 2003 Report Share Posted April 17, 2003 ;). Discrete maths sucks - why on earth are you doing it if you're not in uni? Do some complex analysis instead - proper maths :) I would help ordinarily, but I really want to get as far away from work as possible today - however, I will recommend www.sosmath.com to you :D Oh, just as a hint if inverse of M = N then: NAM * NAM = NAAM soo A to the n is gonna be M * (NAM)to the n * N Link to comment Share on other sites More sharing options...
Guest arunhallan Posted April 17, 2003 Report Share Posted April 17, 2003 What avatar?? ;) I meant im not at uni as in im on easter break (so i cant ask my lecturers). And im doing comp sci, discrete maths is just 1 of the options Link to comment Share on other sites More sharing options...
