Jump to PostWhat about a taylor series approximation... The theory is rooted in calculus, but you can probably manage by simply applying the formulae and ignoring the theory (FYI series and taylor approximations are typically covered in a Calc 2 course).

Here are the approximations (scroll down to the "series definition" …

Cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! ...

Cos(x) = Sin( x - 90 ) ; //assuming x is in degrees

Tan(x) = Sin(X)/cos(X)

"!" means factorial.for example to calculate Sinus you can do this :
