# Math Help - Re-arrange to Find V

1. ## Re-arrange to Find V

Tr = 0.5SV^2(Cdo+((4W^2)/(AR*e*pi*V^4*p^2)))*p

2. ## Re: Re-arrange to Find V

Your equation is essentially of this form:

$T_r = Av^2 + \frac B {v^2}$

Where $A$ and $B$ are constants. You can rearrange to put it into this form:

$Av^4 -T_r v^2+B = 0$

Now solve for v^2 using the quadratic equation.
