Y = cosh(X) returns the hyperbolic cosine of the elements of X. The cosh function operates element-wise on arrays. The function accepts both real and complex inputs.

cosh − 1 (x) = log (x + x 2 − 1). For complex numbers z = x + i y , as well as real values in the domain − ∞ < z ≤ 1 , the call acosh(z) returns complex results. Extended Capabilities

Compute the hyperbolic cosine function for the numbers converted to symbolic objects. For many symbolic (exact) numbers, cosh returns unresolved symbolic calls.

Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of sinh(x), exp(x), and exp(-x). As expected, the sinh curve is positive where exp(x) is large, and negative where exp(-x) is large.
