I know this is a very low level question, but I honestly can't remember how this is done. I want to solve for y with this: $ x = 2.0 \cdot \arctan\left(\frac{\sqrt{y}}{\sqrt{1 - y}}\right) $ And I thought I could do this: $ \frac{\sqrt{y}}{\sqrt{1 - y}} = \tan\left(\frac{x}{2.0}\right) $
But it seems like I've done something wrong getting there. Could someone break down the process to get to $y =$ ?
Again, I know this is very basic stuff, but clearly I'm not very good at this.
