take the secant of a number in ruby

To take the secant of a number in Ruby, you can use the Math module which provides various mathematical functions including trigonometric functions. The secant of a number x is equal to the reciprocal of the cosine of x. Therefore, you can use the following code to find the secant of a number:

main.rb
x = 45  # number in degrees
radians = x * Math::PI / 180  # convert degrees to radians
secant = 1 / Math.cos(radians)  # calculate secant

puts secant

In this code, we first define the number x for which we want to find the secant. We then convert the number to radians using the formula radians = x * Math::PI / 180. Finally, we calculate the secant of the angle using the formula secant = 1 / Math.cos(radians).

You can replace the value of x with any other number to find its secant.
