The hyperbolic tangent tanh x is the ratio of which two functions?
Asinh x divided by cosh x
B1 divided by cosh x
Ccosh x divided by sinh x
Dsinh x times cosh x
Answer & Solution
Correct answer: A. sinh x divided by cosh x
By definition tanh x equals sinh x over cosh x, which simplifies to (e^(2x) - 1)/(e^(2x) + 1).
