Yes i know the factorisation problem is hard. I am workin with RSA encryption so we know two large primes, the product of which is N this is what i want to do euler phi on.
Since N is the product of two primes (p and q) is phi(N) simply (p-1)(q-1)?
Ok thanks i'll have a go at it. I don't have PARI/GP but i mite try and download it, i generally use MATLAB cus it relativly easy. Its not a homework question, a lecture mentioned it and I am just trying to understand it!
Thanks for your comments!
How do i comput the euler phi function of a large interger?
i know that if p is prime then phi(p)=p-1 and I've found a formula for computing non primes but i don't know how to implement in something like Matlab.
Does anyone know how?

Is it correct that when turning there are lateral friction forces that oppose the inertial 'centrifugal' force? i.e. towards the centre of curvature
