THX for that Acer. I just changed a line in your code S[c]:=T[t-1] to S[c]:=t to output the numbers.

for fun, there is the Zodiac killers cipher (one of them). theres no key and no spaces between words

thx to all, esp acer, works like a charm!

Can i have a procedure which does the reverse?

i.e given input "this", output the word pools: t8,t4,t4,t7

in excel i guess i would use the Lookup function but how in maple?

Thanks Alec.

I have this function f(n)=1/4+1/2*n-1/4*(-1)^n

If you try to plot it using

plot(f(n), n = 2 .. 6);

you get an empty plot with complex var warning.

I guess I could do a point plot of domain integer n values which produces a real integer range, but i prefer a line plot.

Thanks Alec.

Nice article.

I was wonding if you (or someone) could derive the "intersection of the line normal to the graph of , namely

Mr Acer

The boundary conditions R1[y](0)=20 sqrt(3)/3 and R2[y](0)=-10*sqrt(3)*(1/3):
How were these derived? pythagorus presumably. can u show me?

thanks Robert and Alec

thanks Robert and Alec

thanks 4 the code (and everyones responses)

i can't wait to play with it,  but am overseas (Bangers) at the moment with no access to Maple.

Sorry for being thick, but i wouldnt know how to code Floyd's Algorithm.
