Re: Help with 3D rotationI think you could divide the area up into parts as a start. igloo myrtilles fourmis #10 20051231 12:00:42

Re: Help with 3D rotationI don't understand a lot of this rotation, but here are some questions. igloo myrtilles fourmis #15 20060101 02:32:07
Re: Help with 3D rotationAlso I was wondering if you considered that if the function is rotated, Last edited by John E. Franklin (20060102 07:52:02) igloo myrtilles fourmis #16 20060101 02:50:02

Re: Help with 3D rotationAs you see the coordinates of A in the second coordinate system A=={x',y'}II are equal to the coordinates of point A1 =={x',y'}I, which is A, rotated 45deg clock. IPBLE: Increasing Performance By Lowering Expectations. #20 20060102 07:46:19

Re: Help with 3D rotationAnd here's the proof thingy: But (rectangular with 45 deg) so S = INEGRAL  S2.
