Monotonicity: The cosh function is monotonically increasing on the interval [0, infinity), and monotonically decreasing on the interval (-infinity, 0]. Hyperbolic identity: The cosh function satisfies the hyperbolic identity cosh^2(x) – sinh^2(x) = 1. Examples Now let’s look at five examp...
The hyperbolic cosine satisfies the identity cosh(x)=ex+e−x2. In other words, cosh(x) is the average of ex and e−x. Verify this by plotting the functions. Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of cosh(x), exp(x),...

Use the definition of cosh: cosh(0) = (exp(0) + exp(-0))/2 = 2 / 2 = 1. Use the identity cosh2x − sinh2x = 1 along with the fact that sinh is an odd function, which implies sinh(0) = 0. Read the answer from the graph of the hyperbolic cosine function. Use an onlin...
