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 appreciate some help.

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

Is this what you mean?

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}}
 
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:
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}}
 
Thanks for correcting my error, krab. :)
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
