Hello There,
I'm after a little advice; I have data collected during experimentation that was designed to determine the improvement of two groups of subjects between a pre and a post-test. The results are as follows:
Pre & Post test numbers represent the number of errors made
Group 1...
Hey again;
It doesn't seem to be my day for spotting the obvious;
I've come across this problem now:
2^{8n}\exp^{2ni\Pi} = 2^{8n}
This imples that exp^{2ni\Pi} = 1, i know that exp^{i\Pi} =-1, but is that related?
hmm, Latex issues...i'll try and fix them :) - sorted

ahh, thanks guys...its been a while since I have done complex numbers, I understand it now :smile:, thanks for the quick and informative replies.
Craig :biggrin:
Sorry, I guess you don't have those fonts installed on your system...i'll put it a different way;
1 + i = root(2) . (cos(pi/4) + i.sin(pi/4))
pi ...being pi(3.14...) :P
so my question is how does (1 + i) equal the value above?
I hope that's clearer?
Craig :)
Hello guys;
I'm after a bit of help here, I may have missed something completely obvious, but I can't seem to figure out the working of:
[FONT="Arial"]1 + i = √2(cos π/4+ i sin π/4)
ie; How does 1 + i equal √2(cos π/4+ i sin π/4)??
any help would be appreciated;
Thanks...
Hello there, I am wondering if you could offer some help on this questoin, I have been attempting to work through it, however cannot see exactly what route I should be taking to try and solve it;
Without using a calculator or table, show that;
2 < log(3) 25 < 3 (log to the base 3 of 25)
and...
