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 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 ...

The motivation for this project is because Python's math module's e constant only contains 16 digits of precision, this program can easily estimate to over 1000 digits for e, sin and cos The program ...
