The function (f) with a period of 2π is defined by: f(x) = cosh (x - 2π) if x ∈ [π ; 3π] a) Using an apoppriate software(excel), give a graph representation of the function(f) for x ∈ [-π ; 5π] Note:...

The function (f) with a period of 2π is defined by:

f(x) = cosh (x - 2π)  if x∈[π ; 3π]

a) Using an apoppriate software(excel), give a graph representation of the function(f) for x∈[-π ; 5π]

Note: cosh (x) = (e^x+ e^-x)/2 and sinh(x) = (e^x- e^-x)/2
