Re: solve for x

Let's consider something a bit easier. Instead of having logs in there, let's just have a simple variable like u.

So now we have u = sqrt(u).
Squaring both sides will give you a quadratic in terms of u, which you can use to find the values of u. You can then work out what x would have to be.


Why did the vector cross the road?
It wanted to be normal.
