Homework Help: Big equation. Yuk

  1. Nov 5, 2005 #1
    Is it possible to make x (or a function of x) the subject of this?!?


    0 = -v.cos(2x) + sin(x).sqrt(v^2.[sin(x)]^2 + 2ah) - (v^2.sin(x).[cos(x)]^2)/(sqrt(v^2.[sin(x)]^2 + 2ah))


    I know its disgusting, but I would really appriciate some help.

    I've converted your equation to LaTeX to help others read this monster.

    Is this what you mean?

    [tex]0 = -v cos(2x) + sin(x) \sqrt{v^{2}[sin(x)]^{2} + 2ah} - \frac{v^{2} sin(x) \cdot [cos(x)]^{2}}{\sqrt{v^{2}[sin(x)]^{2} + 2ah}}[/tex]

    maybe try converting to expontials and seeing if you can simplify it more

    Perfact, I hope a few ideas come out of this new form. Thanks

    Or rather:
    [tex]0 = -v \cos(2x) + \sin(x) \sqrt{v^2\sin^2(x) + 2ah} - \frac{v^2 \sin(x) \cos^2(x)}{\sqrt{v^2\sin^2(x) + 2ah}}[/tex]

    Thanks for correcting my error, krab. :)
