sorry for my layman terminology, but to my understanding as a coder a function has a name, parameters, arguments and operations. if sin is the name, and its parameters are side opposite and hypotenuse, and its arguments are context dependent, what is the operation itself? am i making sense?

def sin (hypotenuse, opposite):
     ??!?!?!!?

I belive that this may be what you're looking for: https://en.wikipedia.org/wiki/Trigonometric_functions#Right-angled_triangle_definitions

One way to think about it -

The argument to the function is an angle

The operation is:

Draw a triangle with hypotenuse length 1, one angle 90, another angle is the one passed to the function

Divide the length of the side opposite the passed angle by the length of the hypotenuse

Return this value

The other trig functions are the same with different sides being divided.
