Calculate cosine of a value in R Programming – cos() Function

** cos()** function in R Language is used to calculate the cosine value of the numeric value passed to it as argument.

Syntax:cos(x)

Parameter:x:Numeric value

**Example 1:**

`# R code to calculate cosine of a value` ` ` `# Assigning values to variables` `x1 <` `-` `90` `x2 <` `-` `30` ` ` `# Using cos() Function` `cos(x1)` `cos(x2)` |

**Output:**

[1] -0.4480736 [1] 0.1542514

**Example 2:**

`# R code to calculate cosine of a value` ` ` `# Assigning values to variables` `x1 <` `-` `pi` `x2 <` `-` `pi ` `/` `3` ` ` `# Using cos() Function` `cos(x1)` `cos(x2)` |

**Output:**

[1] -1 [1] 0.5
