Syntax

pi

Basic usage

print(pi)

# [1] 3.141593

Exponential value of pi

To calculate the exponential value of pi, use the exp() function.

exp(pi)

# [1] 23.14069

Cos

To calculate the cosine value of pi, use the cos() function.

cos(pi)

# [1] -1 

Sine

To find the sine value of pi, use the sin() function.

sin(pi)

# [1] 1.224647e-16

Tangent

acos(pi)

Output

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

It returns the NaN value.

Arcsin

To calculate the arccos value, use the asin() function.

asin(pi)

Output

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

It returns NaN, too.

Arctan

To calculate the arccos value, use the atan() function.

atan(pi)

# [1] 1.262627

That’s it!
