Some of my friends suggested to use a Timer for this one. Any suggestion for a good head start? Thank...

I was thinking about ngen-ing the application to prevent this, however, then the code becomes architecture dependent. Im not targetting any other architecture/p...
I read in an article somewhere that trig calculations are generally expensive. Is this true? And if so, that's why they use trig-lookup tables right? EDIT: Hmm, so if the only thing that changes is the degrees (accurate to 1 degree), would a look up table with 360 entries (for every angle) be faster? ...
