The hyperbolic cosine function is defined by cosh(x) = \frac{e^... | Filo

The hyperbolic cosine function is defined by cosh(x)=(e^x+e^-x)/(2) (a) Sketch the graphs of the functions y=(1)/(2) e^x and y=(1)/(2) e^-x on the same axes, and use graphical addition (see Section 3.6) to sketch the graph of y=cosh(x) . (b) Use the definition to show that cosh(-x)=cosh(x) | Numerade
