A real tough trig question help will be appreciatedHi, #2 20051114 21:51:26
Re: A real tough trig question help will be appreciatedSinx*Sin2x + Cosx*Cos2x Character is who you are when no one is looking. #3 20051115 03:49:27
Re: A real tough trig question help will be appreciatedHow very elegant and unexpected. Why did the vector cross the road? It wanted to be normal. #4 20051115 04:52:00
Re: A real tough trig question help will be appreciatedwhat do you mean? is it not right #5 20051115 04:56:39
