So this is a physics question (but the part to be asked is mathematical) from Quantum Mech.

In an earlier part of question, I obtain an expression for T:

$\displaystyle T=\frac{4\sqrt{E(E+V_0)}}{2E+2\sqrt{E(E+V_0)}+V_0}$

Then it asks, find a simplified expression for $\displaystyle T$ when $\displaystyle V_0 >> E$

The best way I could come up with to (attempt to) solve this, was to assume E = 0, which would make T=0
