Concavity-Calculus
Determine the concavity for f(x)= 4/x^2-1 I took the second derivative and solved for zeros. I got x=-1 and x=1. However when plugged into the orig. equation this results in 4/0 (undefined). Does this mean there is no concavity?

Calculus Derivative- Taylor Series?
Yes I did get those as my derivatives. Thank you very much for your help Reiny. I did not know which patterns to look for. I think that it would be (-1)^n for the alternating neg. and pos.? Then n! for the factorial? And lastly x^ -(n+1) for the power of x in the denominator? ...
Calculus Derivative- Taylor Series?
let f(x)= x/x-1 find f'(x) f ''(x) and a formula for f ^ (n) * x. I found the first and second derivatives but do not know how to make a general equation for this. I have not learnt the Taylor or Maclaurin Series either. Thank you.
