maybe you can still help me:
im basically trying to solve number 6, so but im just doing the math wrong. the solution posted here does the problem by dividing, i tried subtracting the equations instead: http://www.ece.msstate.edu/~ykoshka/...Solutions).pdf
(1)
(2)
subtracting (2)-(1) i end up with this:
how do i solve this?
why don't you want to use division? it seems a lot easier to get to what you want to get to. also note that the solutions do not use the original equation, but an approximation of it. it would stil be really difficult to solve the equation as you have it. in any case, this looks like physics, and i'm not the expert on that.
