The hyperbolic cosine function, denoted cosh x, is used to model the shape of a hanging cable
Question:
The hyperbolic cosine function, denoted cosh x, is used to model the shape of a hanging cable (a telephone wire, for example). It is defined as cosh x = ex + e-x/2.
a. Determine its end behavior by analyzing and
b. Evaluate cosh 0. Use symmetry and part (a) to sketch a plausible graph for y = cosh x.
