Question

What does the "h" mean in the question "find the limit as x approaches infinity of (sinhx)/e^x ?

Answer 1

hyperbolic sine

Answer 2

sinh(x) is hyperbolic sin function.

h for hyperbolic. there is a button for it on many calculators and you'll want to use the fact that:
\[\sinh(x)=\frac{ e^x - e^{-x} }{ 2 }\]

Answer 3

\[\sinh(x) = \frac{ e^x-e^{-x} }{ 2 }\]

Answer 4

Thank you!
