In a right-angled triangle, the tangent of an angle is:
The length of the side opposite the angle is divided by the length of the adjacent side.
The abbreviation is tan is the following.
tan(θ) = opposite / adjacent
tan in R
The tan() is a built-in R function that calculates the tangent value of numeric value. It accepts a numeric value as a parameter and returns the tangent value. The tanpi() method calculates the tangent of the input value, the multiples of π.
To calculate the tangent in R programming, use the tan() function.
The tan() function takes a numeric value.
x1 <- -45 x2 <- -60 tan(x1) tan(x2)
 -1.619775  -0.3200404
Applying pi to the tan() function
The pi is an inbuilt constant whose value is 3.141593. Let’s pass the pi to the tan() function and see the output.
x1 <- pi x2 <- pi / 3 tan(x1) tan(x2)
 -1.224647e-16  1.732051
Applying a tan() function to Vector
To create a Vector in R, use the c() function. First, let’s create a vector and pass that vector to the tanpi() function.
dt <- c(1, 0.5, -1, -0.25, 0.5, 2 / 3) tanpi(dt)
 0.000000 NaN 0.000000 -1.000000 NaN -1.732051 Warning message: In tanpi(dt) : NaNs produced
That is it for tan() function in R.
