How can you calculate the sine knowing only the degree measure of an angle?

Question

Mathematics

I need some algorithm for calculating the sine, knowing only its degree measure, but I didn’t find anything on the Internet, can you tell me how to do this?

Answer 1

- convert degrees to radians ( * pi / 180), use any standard method for calculating the sine, for example, a function sinfrom the standard library or a Taylor series
- use the Bradis table for degrees, interpolate if necessary

Answer 2

I don't understand what a "degree measure" is.
If you are talking about the angle in degrees, then to convert to radians, it is enough to remember the proportions, class 4 or 5.
180 ° \u003d π rad
x ° \u003d? glad

Answer 3

Well, I don’t even know, you were banned in Google?

Answer 4

Taylor series for sine:

sin(x) = x - x³/(3!) + x⁵/(5!) - x⁷/(7!) + x⁹/(9!) - ...

Depending on what is more important, the speed of calculation or memory, you can use this method or tabular . For microcontrollers, this is more or less relevant, but for "large" systems - I don’t think it’s worth it to run away like that, only if you don’t write a demo, of course.
