Cosh Calculator | Hyperbolic Cosine Function
Use the definition of cosh: cosh(0) = (exp(0) + exp(-0))/2 = 2 / 2 = 1. Use the identity cosh 2 x − sinh 2 x = 1 along with the fact that sinh is an odd function, which implies sinh(0) = 0. Read the answer from the graph of the hyperbolic cosine function. Use an online cosh calculator.

What is the value of cosh (0) ?
limit as h approaches 0 of (cosh(x))/h - Symbolab
h → 0 lim (h cosh (x) ) If x → a − lim f ( x ) = x → a + lim f ( x ) then the limit does not exist h → 0 + lim ( h cosh ( x ) ) = ∞

Why $\\cosh(y)$ cannot be zero in this example?
Therefore $\cosh x$ can never be zero for real values of $x$. Also, when doing the second equation, you get $\cos(x)\sinh(y) = 0$, but this time the solutions split the case into $\cos(x)=0$ and $\sinh(y)=0$ as I did above.

trigonometry - How lim $h->0$ $\sin h/h$ is equal to $1
2018年5月9日 · The precise definition of the limit is a bit more complicated: when we say $$\lim_{h\rightarrow 0}{\sin(h)\over h}=1,$$ what we mean is that for any $\epsilon>0$ (the "degree of accuracy") we can guarantee that $\sin(h)\over h$ is within $\epsilon$ of $1$ just by making sure that $h$ is close enough to $0$; fully formally, that for all ...
