Snale,

Plus, using radians simplifies taking derivatives and integrals. If you use degrees you have to deal with the multiplication constants.

Assuming you use C/C++ try this:

#define PI 3.141592654f
#define DEG2RAD(x) ((x*PI)/180.0f)
#define RAD2DEG(x) ((x*180.0f)/PI)

Also (certainly in MSVC) #include math.h...it seems that there are some other functions also called sin & cos that have a completely differnet numbering scheme...dunno what it is, but it seems to happen if you don't #include math.h

Sod it, forgot that forum removes things between angle brackets

Plus, the variable you use in the Power Series Representation of sin has to be in radians for the series to work. Ask me and I''ll continue .
