    Primitive polynomial in GF(4) ?

    primitive polynomial in GF(4) ?? Hai All, I m required to make a pseudo random generator. I know that i can make that using some Flip flops and XOR gates(in linear feedback shift register configuration ). But the resulting PN sequences will be in Galois Field(2) as the taps for the flip...

    Solving the 2,0,0,5 Sequence Puzzle - Prove Your Answer!

    hi why can't u just try to generate the numbers previous to 4,0, 5,3 ... all the generated numbers should be single digit i got ...11,3,0,4,8,5,7,4, 4,0,5,3,... since we are getting 11 the sequence 4,0 ,5,3 will never appear regards Mahesh

    Completing the Square: x^2+2x+5 is Always Positive

    hai since your answer is a sum of a positive number (4) and square of a function (x+1) with x belonging to the set of real numbers (all integers,fractions both positive and negative ... or simply any number which can be plotted on the real axis) that expression will never be negative...

    When will the walking boy reach school?

    we have distance = 10c So time taken by the boy who is walking = 10c/w minutes S0 the person walking will reach school 10c/w-10 minutes after the cyclist . One interesting thing is the expression can be re wirtten as 10(c-w)/w. 10(c-w) being the relative distance and w being the velocity ...

    Find the path traced out by each ant

    But in that case the condition that " at any instant of time the direction of motion of each ant is directed towards an ant which started from a vertex adjacent to it " will not be satisfied The path i got by drawing it is attached .. I am not very good at sketching :smile: These...

    Find the path traced out by each ant

    Hi guys Please help me work out this problem :cry: The problem is like this There is a square table. On each vertex there is an ant sitting. Now these ants (four of them) starts moving in such a way that at any instant of time the direction of motion of each ant is directed...

    Are there other non-integrable functions besides x^x?

    hai i heard that the function x^x doesn't have any indefinite integral and hence one can't find definite integral by normal methods .. So one has to go for numerical methods , i haven't tried this ... just curious to know if there exist more fuctions in the same class ... regards...

    Uncovering the Mystery of Numbers Divisible by 7

    hi , repeating an integer, x (say), six times is not the same as multiplying it six times ... i m sorry but i think u haven't got my question correctly... it is like this suppose x is an n digit number repeating it 6 times gives a number y= 1*x + 10^(n)*x + 10^(2n)*x + 10^(3n)*x+...
