1. The problem statement, all variables and given/known data Express the function cosh(2x)+2 sinh^2(x)= in terms of exponential functions. 2. Relevant equations 3. The attempt at a solution i have an answer but im not sure if its right can someone check please. =1/2 (e^2x+e^(-2x) )+1/2(e^2x-e^(-2x)) if this is right i need some help simplifying.
