Solving p = (1-1/k sq'd) for one unknown

[davidt]

I have the formula p = (1-1/k sq'd)

How can I change this around so that if I know the value of p, I can solve for k?[/tex]

\(\displaystyle p = 1 - \frac{1}{k^2}\)

\(\displaystyle \frac{1}{k^2} = 1 - p\)

\(\displaystyle k^2 = \frac{1}{1-p}\)

\(\displaystyle k =\)±\(\displaystyle sqrt{\frac{1}{1-p}}\)
