hello! I am 13 and Im learning 3d concepts, but I dont know too much of maths, so does anyone konw where I can learn things like Sin Cos Tan online? .lick

Try searching for trigonometry on the web.
Geometry might be a winner as well.

There are some resources on gamedev.net that might be helpful, though I didn''t see a basic introduction to trigonometry.

Also, you might try mathworld, though it isn''t really meant as an introduction either.
