Homework Statement
I am supposed to solve this equation for y.
Homework Equations
0=-(x+0.91)/(y^2+(x+0.91)^2 )+ (x-0.91)/(y^2+(x-0.91)^2)
The Attempt at a Solution
I moved one of the terms to the other side and saw no way to get the solution doing that so then I got a CD by doing this:
[ (x+.91)(y^2 + (x-0.91)^2) - (x-0.91)(y^2+(x+0.91)^2) ] / [ (y^2 + (x+0.91)^2) (y^2 + (x-0.91)^2 ]
Then expanded
{xy^2 + x(x+0.91)^2 - 0.91y^2 + 0.91(x+0.91)^2 - [xy^2 +x(x+0.91)^2 - 0.91y^2 - 0.91(x+0.91)^2]} / [y^22 + y^2(x+0.91)^2 + y^2(x-0.91)^2 + (x+0.91)^2*(x-0.91)^2]
I don't really think expanding helps at all but I didn't know what else to so cause I didn't see a solution from the earlier eqn.
Any suggestions?[/B]
