take the cosecant of a number in ruby

To take the cosecant of a number in Ruby, you can use the Math module and the sin^-1 function to compute the sine of the angle and then take the reciprocal. Here's an example:

main.rb
x = 30 # angle in degrees
csc_x = 1 / Math.sin(Math::PI * x / 180)
puts csc_x # outputs 2.0

In this example, we first define the angle x in degrees. We then use the Math.sin function to compute the sine of the angle in radians by converting x to radians using the formula Math::PI * x / 180. We then take the reciprocal of the sine to obtain the cosecant of the angle and store it in the variable csc_x. Finally, we output the result using puts.
