I have a maths question to do with games. I haven't done maths/physics for years so forgive my basic questions. q)If I have an object on the screen which moves in a circular direction (eg say something moving in the XY plane only)and I know the equation it moves to, can I use differentiation from school to work thigs out like velocity,acceleration etc q) Can you use a lot of maths and physics from school when doing 3d modelling, does it have a use eg differentiation,anit-differentiation, partial equations etc . I never though I would find a use for this stuff.

That's exactly what a derivative will let you do.
v = dx/dt (and/or dy/dt)
a = dv/dt

AFAIK, 3d modelling doesn't have a lot of interaction with calculus. It'd have more to do with linear algebra (which in my experience, didn't get very relevant with regards to graphics and such until first-year math in university)

calculus (derivatives)works out speeds, acceleration etc and from memory it does so in a curved line as well.
I thought this might be used but you says it doesn't.

oh well
