The tan() is an inbuilt function in Ruby returns the tangent of a given angle expressed in radians which is in range [-inf, +inf]. The returned value is in range [-inf, +inf].
Syntax: Math.tan(value)
Parameters: The function accepts one mandatory parameter value whose corresponding tangent value is returned.
Return Value: It returns the tangent value.
Example 1:
#Ruby program for tan() function #Assigning values val1 = 1 val2 = 0 val3 = 989 val4 = -8932 #Prints the tan() value puts Math. tan (val1)
puts Math. tan (val2)
puts Math. tan (val3)
puts Math. tan (val4)

Output:
1.5574077246549023 0.0 -0.6866146142998235 -0.48563022371184766
Example 2:
#Ruby program for tan() function #Assigning values val1 = -1023 val2 = 0.67 val3 = 98 val4 = -39 #Prints the tan() value puts Math. tan (val1)
puts Math. tan (val2)
puts Math. tan (val3)
puts Math. tan (val4)
