are specificC combinations of ex ponential functions that appear in application frequently enough that they have their own names. For example, the "hyperbolic cosine function" is given by et + e-t cosh x the "hyperbolic sine function" is given by et – e- sinh x = 2 and the "hyperbolic tangent function" is given by sinh x tanh x = cosh x marks). Use the definitions above to show that d tanh x dx 1 cosh?.

rks). The "hyperbolic trigonometric functions" are specific combinations of ex ponential functions that appear in application frequently enough that they have their own names. For example, the "hyperbolic cosine function" is given by e" +e* cosh x the "hyperbolic sine function" is given by et – e- sinh x = 2 and the "hyperbolic tangent function" is given by sinh x tanh x = cosh x marks). Use the definitions above to show that d tanh x dx 1 cosh? x marks). The velocity of a water wave with length L moving across a body of water with depth d is given by 2nd tanh L V = 76 where g represents the acceleration due to gravity (a positive constant). What happens to the velocity as the wave length increases without bound? That is, evaluate lim v Hint: Find lim v² first, and then use that to answer the question above.
