Hyperbolic arc cosine online calculator (inverse hyperbolic cosine)
You can calculate the hyperbolic arc cosine (inverse hyperbolic cosine) of a given number to input the acosh word and numbers in the above form as follows.
In the above example, the calculator shows the hyperbolic arc cosines of 1, 2, 3. The acosh word works as a command to calculate the hyperbolic arc cosine. All numbers you input should be separated by one space.
Let's input acosh and numbers in the above form!
Error handling
The hyperbolic arc cosine function is the inverse of hyperbolic cosine so the domain of hyperbolic arc cosine is $[1,\ \infty)$. If you input a number that is smaller than 1, the calculator skips.
In this case, 0 and -5 are not in the function's domain. The calculator returns only the acosh() of 2 and 1000.
