Hi

I am doing some heavy maths code at the mo.

I found a practical use for Sin and Cos (to spin the camera around in a circle).

I was wondering if any1 could enlighten me as to the use of Tan and Atn. I know Tan Angle = Opposite / Adjacent and I assume Atn Angle = Adjacent / Opposite (having briefly read a help file on Atn).

Could any1 give me an example of their practical uses with reagrds to DX8 and Graphics. Also any SIMPLE and clear website links on this stuff would help loads.

I guess since Im working with 100s of triangles I better brush up on my trigonometry.

Cheers guys

Dan
