How to find the coordinates of a point on a circle, knowing the coordinates of the center of the circle, the radius and angle between the horizontal axis and the diameter passing through the desired point, without using trigonometric functions?
- And what is the angle "between the horizontal axis and the diameter" in what is set, in degrees or a vector or something else? - Kromster
- @KromStern, most likely, it is necessary to convert the polar coordinates to Cartesian. So in degrees. - ߊߚߤߘ
- @Arhad: I would like to hear the exact terms from the author. We can only guess .. - Kromster

In my opinion, nothing. Is that considered trigonometry decomposition in a Taylor series. Just once the angle is specified, and not, say, its tangent or something else in this spirit - then it would be possible to perform the appropriate transformations from one function to another.
If it's not a secret, what is the reason for this limitation?

If you just need to get rid of an explicit call to sin, cos, etc., then take formulas with trigonometric functions, and then simply replace sin with some kind of approximate calculation algorithm:
- Table Interpolation
- CORDIC
- Taylor series
