Returns the cosine of a number in degrees.
The cos[] function is a function that returns the cosine of a number. The cosine of an angle is a value that ranges from -1 to 1, and it is defined as the ratio of the side of a right triangle adjacent to the angle to the hypotenuse. The input to the function is an angle in degrees, and the output will be a value between -1 and 1.
For example, cos[0] would return 1 and cos[90] would return 0.
Cosine is commonly used to calculate the projection of a vector on the x-axis or y-axis in physics and engineering, as well as in trigonometric identities and equations.

#<result> = cos[0] (print,#<result>)
result: 1
#<result> = cos[45] (print,#<result>)
result: 0.707107
#<result> = cos[90] (print,#<result>)
result: 0
