I'm trying to understand some of the trigonometry functions I need to use in the games I wish to create. Can someone correct me if i'm wrong and with an explanation. There are basically two different types of coordinate systems. Cartesian and Polar. Cartesian is finding a new x, y location by knowing the last x, y location and calulating the next. Polar finds the new x, y location by a vector length and angle. Is this right? I'm trying to understand the cos/sin functions better. cos/sin take radians as arguments, by multiplying cos/sin by a vector length you will get the new Cartesian coordinates? Is that was these functions are for? Can someone shed some light on cos/sin/tan and vectors or post a good tutorial? Thanks for reading. Erick
