There has been lurking in my mind a question for way too long, without being able to find a suitable, satisfying answer.
How are sin(), cos(), and tan() functions calculated on a calculator or computer?
I understand that mathematicians use the famous unit circle to define the trigonometric functions, but if
So we are still left with the question, how is sine, cosine and tangent computed?
All the books and references that I read basically just suggest to use the calculator, in other words computed by magic or dogma.
Edit: I now remember that they use the Pythagorean theorem.
√1/2 = o
But how do they compute the rest of angles?
