For all you algebra buffsI need to transpose a formula and my algebra isn't up to it. I would welcome any suggestions or solutions. the formula is: #2 20090530 07:42:26
Re: For all you algebra buffsAlgebra won't be enough. You have the points A = 0, A = 1, and A = 2 all give the value S = 0. This means the inverse (i.e. solving for A) won't be a function. You can locally come up with approximations for the inverse where the derivative with respect to A is nonzero, but this is about all you can do. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
