Hi,
It seems I've forgotten more of my algebra than I thought. I am putting together a spreadsheet to help a few archers determine how to change their point of aim for up- and downhill shots. I would like to reduce/rearrange the following expression so that A and B are not found on the same side of the equality, but after 30 minutes can't seem to do it. Ideally, I would like B to be a function of A,C, and D which are known in this setting. Any help is appreciated, even more so if the steps are sketched. -Seth
tan (A) = tan (B) - (9.8*cos(A)*C)/(2*(cos(B)*D)2)
