Homework Help: Osculating Circle

  1. Nov 8, 2016 #1
    1. The problem statement, all variables and given/known data

    I know I would use the curvature equation |f''| / [1-(f')^2]^3/2 and then take the limit of that to -1. I just don't understand why I have to take the limit of the curvature and when I take the limit of the curvature I get |-1| / (13)^3/2 when the answer should be 2.
