cosh() Function in R with Example

Hyperbolic functions in R calculate the hyperbolic cosine, sine, tangent, and their inverses, arc-cosine, arc-sine, arc-tangent.

cosh() Function in R

To calculate the hyper tangent of cosine value in R, use the cosh() function. The cosh() function calculates the hyperbolic cosine of the given value.

Syntax

cosh(x)

Parameters

The x is a column to compute on.

Example

Let’s calculate the cosh value of 1.

cosh(1)

Output

[1] 1.543081

Let’s calculate the cosh value of 0.

cosh(0)

Output

[1] 1

Calculate cosh() of complex number

Define a complex value and pass that value to the cosh() function.

d <- 5 + 1i
cosh(d)

Output

[1] 40.09581+62.43985i

Plot the cosh() function to a graph

We can use the seq() function to create a series of values and pass that to the plot() function, which will create a line chart.

dt <- seq(-1, 1, by = 0.05)
plot(dt, cosh(dt), typ = "l", col = "red")
abline(v = 0, lty = 6, col = "blue")

Output

cosh() Function

Applying cosh() function to a Vector

To create a Vector in R, use the c() function. Then pass that vector to the cosh() function.

rv <- c(-1, 0.5, 0, 0.5, 1)
cosh(rv)

Output

[1] 1.543081 1.127626 1.000000 1.127626 1.543081

Passing a pi to the cosh() function

The pi is an inbuilt constant in R programming, and its value is 3.141593.

Let’s find the pi constant’s cosh() value.

cosh(pi)

Output

[1] 11.59195

Let’s see another example of pi.

cosh(pi / 4)

Output

[1] 1.324609

That is it for cosh() function in R programming.
