i just fixed up my dads computer and i need to put a new password for his account so all my little brothers don't go accessing it. i want to be a little creative. i want to create a password but only leave him a hint so he has the figure the password out himself. i was thinking i should make the hint something mathematical or something physics related because he is an electrical engineer. but i can't think of anything short yet sophisticated enough so only my dad can figured it out. can anyone help me please! thanks in advance

assign each letter in the alphabet a nr, say from 1 to 26, then create a function that would assign a specific nr. to a letter in alphabet. say [tex]f(x_i)= x_i+2[/tex] where x_i wold be your letter in the alphabet, translated as a nr. For example, you might want your pasword to be :ME. then here it is how you would code it according to that function. The nr associated with M is 13, and wih E=5 so

instead of writting M you would write K, because K=11, so f(K)=K+2=11+2=13=M,
simmilarly

instead of E write C, because f(C)=C+2=3+2=5=E.

But you can make a more complicated function, or make a function that assigns nr, to letters differently rather than in order.

Have fun with that!
 
thats a good one but that would take longer than i like. i need something short but it can only answered by a mathematician, u know what i mean.

First, that's not long at all. Second i don't know what u really mean, so try to explain what are you specifically looking for...lol...
 
"To convert a function from the time domain to the frequency domain, one must do a ______ transform."

The answer would be "Fourier."
