Write three separate MATLAB user-defined functions to calculate the hyperbolic sine, cosine, and tangent functions: sinh(x) = cosh(x) = tanh(x) = - e 2 e* + e-x 2 exe-x ex + Use your functions to plot the shapes of hyperbolic sine, cosine and tangent for values of x between - 5 and +5. Note: You will have one m-file for each function and another m- file for calling each function and plotting results. This will give a total of 6 m-files.
