this is where the problem arose for me because there are x^5 and so on terms in the expansion how can these all be expressed as O(x^3) or is this just an estimation??
thankyou for the help and any future help

Using now the MacClaurin series of that HallsofIvy wrote we get , and
this is less than some constant times when x is close enough to zero (can you see why?)
