1. The problem statement, all variables and given/known data For example cosh(x) = 1+x2/2!+x4/4!+x6/6!+.... 2. Relevant equations 3. The attempt at a solution So plugging in x=0 you get that coshx = 1 at the origin. The approximate graph for the coshx function up to the second order looks like a 1+x2/2! graph, but what about graphing coshx to the term afterwards? and so on.
