Re: I need to review modulus function

Thank you very much for reviewing the problem and solving it.

My review for the question from 800score.com is as follows:
For understanding the above problem the modulus function should be clear. You can

If you know the modulus function, then you know that |x|= x if x>= 0, |x|= -x if x< 0. So, here, the function will have different forms when

Can anyone help me understand this questions from 800score.com ? I stumbled upon this questions when i was reviewing the concepts for modulus

Excellent! I think this is what I was trying to form earlier.

Oh, good fun!
tan(x) is not O(tan(tan(x))) for the same reason, infinity is

For all c, k, n there exists x>k suct that tan(x)>cn^n:

Pick a positive integer m so that m*pi>k. Suppose n>1.
