Alright, I understand the definitions of the trigonometric functions, how it is a ratio between the lengths and hypotenuse. However, I wish to deepen my understanding how what goes on behind the scenes when I input sin(x degrees) into my calculator to get an output. How is the calculator able to get from this, e.g.sin(56), to that: 0.829 (3 s.f.)?

might not be how calculators evaluate trig functions, but one way to do it is with an infinite sum.

the more of these terms you add up, the closer your answer gets to the actual value of sine.
