## Algebra Simplification

Problem:

I need to simplify the x equation as far as I can, the y equation is x multiplied by it's conjugate, and the z equation is a failed attempt at further simplification. The last line is me checking which of the 3 (x, y, and z) equations are equal.

Basically, I need to take the y equation, keep not change the y at all, and get the other side simplified as much as I can.

Thanks!

Stick instead with your "x" formula, and you may rewrite this, if not simplifying, as: $$x=\frac{\sqrt{\frac{A}{B}}(\sqrt{\sin^{2}\theta-\frac{C\sqrt{B}}{\sqrt{A}}})+\sin\theta}{B}$$ This should also tell you where you went wrong in your "z"-expression.
 Thanks, that looks better. But uh... Plug in the numbers I did in my x equation and you get 0.8164965809... (2/3)^.5 = 0.8164965809... So somehow my x equation simplifies to just (A/B)^.5
