SUMMARY

The discussion centers on rewriting a complex expression involving variables τ, α, ε, and η into a simplified form. The original expression is \frac{\tau }{{\alpha - \varepsilon + i\eta }}\left( {1 + \frac{\tau }{{\alpha - \varepsilon + i\eta }}G} \right), and the goal is to express it as \frac{\tau }{{\alpha - \varepsilon + f\left( \alpha \right)}}, where f is a function of α. Participants express confusion regarding the presence of τ² in the original expression and its absence in the final form, indicating a potential oversight in their calculations. The discussion emphasizes the importance of verifying each step in the transformation process.

Homework Statement


Hi

I have an expression on the form

<br /> \frac{\tau }{{\alpha - \varepsilon + i\eta }}\left( {1 + \frac{\tau }{{\alpha - \varepsilon + i\eta }}G} \right)<br />

where i denotes the complex i. I have to bring this into the form

<br /> \frac{\tau }{{\alpha - \varepsilon + f\left( \alpha \right)}}<br />

where f is some function. I have been sitting with this for most of the morning. Can you give me a hint on how to get there? I have tried many ways of rewriting the expression, but still far from the above.

Hi Niles! :smile:

I don't get it …

there's clearly a τ2 in the expression, so how can it not be in the answer? :confused:

What is the context?
 
I have solved an equation, and I am asked to show that the result I get is equal to the last expression above. Perhaps I have made an error. I'll re-check.
