Transfer Function
I simply have no idea how to go about this question, I've asked around and I was directed to black's formula, but that did not end up being much of a help. I must be missing something and it seems like their should be an easier mathematical way of solving this:

lets assume that the system may be represented by the block diagram shown in the attachment.

Then:

$\displaystyle V_o=T_1 [V_i-T_2V_o]$

Then:

$\displaystyle V_o[1+T_1T_2]=T_1V_i$

$\displaystyle V_o=\frac{T_1}{1+T_1T_2}V_i$
