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 ...

Optical or magnetic sensors for position and angle sensing in motion control systems generally provide sine and cosine signals for conversion. The 90° phase shift between sine and cosine allows ...

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...

Both sin and cos are functions of one (undetermined) variable, and can be called, but when one performs arithmetic on them this changes. Maybe there should be a CallableSymbolicExpressionRing with an ...

I'm trying to define a body force function that goes into PDE it has trignometric functions like sin and cos, I found out an example in your Demos "elasticity_plate.py". lmbd = 1.0 mu = 0.5 Q = 4.0 ux ...
