Can you simplify this cubic cosh formula? How to evaluate expressions with hyperbolic trig functions. We write cosh^3 in terms of cosh3x, similar to double angle formulas in trig. We do this by writing cosh in terms of exponential functions and using the binomial theorem. This has a very interesting application to plastic ratios and allows us to write it in a more simplified form. This video will make you go Oh My Cosh!!!
