IMO algebra and 5th year basic math (trig etc), my math knowledge is poor but if you know algebra and use some common sense then you can convert any equations etc you need to basic easily enough, the only thing I lack is a knowledge of these dot product vector thingys (that didn`t get taught back in 1976/77 when I left school) that should make the 3d math easier (or so I understand) , but I just use the old vector math system or 3d co-ordinates and they seem to provide the results I want, you don`t NEED new math to do the job, just some of the functions would make things easier (or so I understand), then again I never had a problem so complicated I felt obliged to take the time to learn the "new math" system.
