Ok, so this is the original equation:

2π√(x+t) = 4

This is it "correctly" rearranged for x:

x= 4/π^2 -t

and this is what I got instead:

x= (4/2π)^2 -t

How, was from the oringal: Dividing both by 2π, Squaring both sides, then subtracting t from both sides. However what I thought would be right is quite far from what the book says is right. Anyone see where I went wrong?

You just didn't follow all the way through.

(4/2pi)^2 reduces to (2/pi)^2, this quantity is then squared to get 4/pi^2

Your math made me open my adv calculus textbook. It talked about Newton's Trident.

It blew my mind.

Oh. LOL Now I feel like an idiot for not thinking of that. Thanks man.
