1. The problem statement, all variables and given/known data Prove that sinh(kt) is of exponential order |k|. Find M>0, c>=0 and T>0 to show that |f(t)|= Me^(ct), t>T 2. Relevant equations |f(t)|= Me^(ct), t>T 3. The attempt at a solution I'm looking at the graph of sinhkt (i graphed a few values of k) and indeed it is of an exponential order. Now, |sinhkt|<=Me^(ct), t>T sinhkt isnt bound. So c=/=0=/=t oh boy... help?
