The acosh() function in R is “used to calculate the inverse hyperbolic cosine of a value“. The hyperbolic arccosine is the inverse of the hyperbolic cosine function, which means that acosh(x) = cosh-1(x).
x: It is a numeric value, array, or vector.
To calculate the hyperbolic arccosine in R, you can use the acosh() function. The inverse hyperbolic cosine function is defined by x == cosh(y).
If you pass the 0 to the atanh() function, it will return 0.
Define and pass a complex value to the acosh() function.
dt <- 8 + 9i acosh(dt)
We can use the seq() function to create a series of values and pass that to the plot() function, creating a line chart.
dt <- seq(-1, 1, by = 0.01) plot(dt, acosh(dt), type = "l", col = "red")
Warning message: In acosh(dt) : NaNs produced
The function returns the NaN value, so it can’t draw a graph based on that value.
To create a Vector in R, use the c() function. Then pass that vector to the acosh() function.
rv <- c(-1, 0.5, 0, 0.5, 1) acosh(rv)
 NaN NaN NaN NaN 0 Warning message: In acosh(rv) : NaNs produced
The pi is an inbuilt constant in R programming, and its value is 3.141593.
Let’s find the pi constant’s acosh() value.
Let’s see another example of pi.
acosh(pi / 4)
 NaN Warning message: In acosh(pi/4) : NaNs produced
That is it for acosh() function in R.
