This post begins a series on how sin and cos are calculated in the c language standard math library on a typical Linux system. Because Python floats are really c doubles, what I write here applies to ...

Trigonometry is often aligned with right-angled triangles only. However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine ...

(I have no idea why POLYNOMIAL is defined in terms of POLYNOMIAL2 in this way. Neither is used anywhere else in the file.) and these numbers are close to, but not the nearest floats to, the ...

The three sides of a right-angled triangle have special names. The hypotenuse (\(h\)) is the longest side. It is opposite the right angle. The opposite side (\(o\)) is opposite the angle in question ( ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...

Thanks for your library. I was wondering if you could document how you determined the polynomials for sin and cos. I tried using sollya with my limited knowledge to find some myself, and always ended ...
