Thanks very much for the reply; with that info: \frac{di_1}{dq_1} = 2q_1+1 \frac{dv_1}{dq_1} = U_T(\frac{2q_1+1}{q_1}) And from this I get \frac{di}{dv}=\frac{ \frac{di_1}{dq_1} }{ \frac{dv_1}{dq_1} }= \frac{q_1}{U_T} I'm not sure if this is correct. For one thing, I'm not sure how I could...

This isn't a homework problem exactly but my attempt to derive a result given in a textbook for myself. Below is my attempt at a solution, typed up elsewhere with nice formatting so didn't want to redo it all. Direct image link here. Would greatly appreciate if anyone has any pointers.
