f=(x)cosh^(-1)((x)/(2))-√((x)^(2)-4) f'=

find f' of f=(x)cosh^(-1)((x)/(2))-√((x)^(2)-4)

How to derive cosh (3x) in terms of cosh (x) and sinh (x) ? Initially I start with 1/2 (e^3x+e^-3x)...

how do I solve cosh((1+j)/2) to form of a+jb????

Evaluate: (b) cosh(π) (c) cos(iπ)

Sinh x + 2 = cosh x
