The actual methods by which sin and cos are calculated are rather complicated (I’ll return to this in future posts) and the detail depends on exactly what system you are using, but if you assume that ...

This post is about 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 will apply to Python ...

The sine and cosine functions are provided in the Python math library. These functions are used to relate angles to rectangular (x,y) coordinate systems and can be very useful in computer game design.
