ok...i have an exam on analysis monday morning, but until then I have no opportunity to speak to any lecturers and im stuck on a past paper question that keeps coming up.
I know that for the chebyshev norm of a function such as
f(x)=2x^3 +3x +4 xe[0,2] or something, you subsititute in the end points and then differentiate and the highest answer will be the chebyshev norm, but what if the function was of the form
f(x)=(x+1)^2 / (x^2+1) xeR?????
do you just differentiate as normal then make =0 and find values for x?? or is there a theorem to use for functions of this kind??
If nobody is sure, or anyway I would really appreciate if anyone knows of any good websites to help with explaining analysis.

I would guess that you would just differentiate it and set it equal to zero since f(x) it is bounded. You might just try Google. Sometimes you can find the exact problem online. Also, there are some books online as .pdf that might do well at explaining the process.
