I hadn't realized that he wanted to solve the last equation for t.
I don't think that the solution is that much sensible as to the guess values for t.
There simply are two different solutions for t depending on how you take the square root of (1-t)^2. You assumed its 1-t and you would get the other solution if you assume its t-1.
With the original equation you get one of the two solution depending on the guess value (<1 or >1).
