Pi in R

Pi is a built-in R constant whose value is 3.141593. The pi constant is the ratio of the circumference of a circle to its diameter. When you define a pi, please note that p of pi is in lowercase.

Syntax

pi

Example

print(pi)

Output

[1] 3.141593

The value of the pi constant in R is 3.141593.

Calculate the exponential value of pi in R

To calculate the exponential value of pi in R, you can use the exp() function.

[1] 23.14069

Output

[1] 23.14069

Calculate the cos value of pi

To calculate the cosine value of pi in R, you can use the cos() function.

cos(pi)

Output

[1] -1

Find the sine value of pi.

To find the sine value of pi in R, you can use the sin() function.

sin(pi)

Output

[1] 1.224647e-16

Find the tangent of pi in R

To calculate the tangent of pi in R, you can use the tan() function.

tan(pi)

Output

[1] -1.224647e-16

Compute the arccos value of pi

To calculate the arccos value of pi in R, use the acos() function.

acos(pi)

Output

[1] NaN
Warning message:
In acos(pi) : NaNs produced

It returns the NaN value.

Compute the arcsin value of pi

To calculate the arccos value of pi in R, use the asin() function.

asin(pi)

Output

[1] NaN
Warning message:
In asin(pi) : NaNs produced

It returns NaN too.

Compute the arctan value of pi

To calculate the arccos value of pi in R, use the atan() function.

atan(pi)

Output

[1] 1.262627

sinpi() in R

The sinpi() function in R is used to compute the sine value of the input, which is the multiple of pi.

Syntax

sinpi(x)

Parameters

The sinpi() function takes x as a numeric value, array, or vector.

Example

sinpi(0.75)
sinpi(0.5)
sinpi(1)

Output

[1] 0.7071068
[1] 1
[1] 0

Example 2

sinpi(1 / 4)
sinpi(1 / 5)
sinpi(2 / 5)

Output

[1] 0.7071068
[1] 0.5877853
[1] 0.9510565

That is it for the universal constant pi in R.
