/*
This program demonstrates the usage of the following trigonometric functions
from the math.h library:

    sin: calculates the sine of an angle in radians
    cos: calculates the cosine of an angle in radians
    tan: calculates the tangent of an angle in radians
    asin: calculates the arc sine (inverse sine) of a number and
	returns the angle in radians
    acos: calculates the arc cosine (inverse cosine) of a number and
	returns the angle in radians
    atan: calculates the arc tangent (inverse tangent) of a number and
	returns the angle in radians

The program converts an angle from degrees to radians using the formula:
radians = degrees * (M_PI / 180.0). The output will show the result of each
trigonometric function call.
