Question

Prove That :
$\frac{x { \alpha }^{2} + y \alpha + \gamma }{x \alpha + y + \gamma \ { \alpha }^{2} } = \alpha$
Where x, y and gamma are variables and alpha equals to omega(W).
(W = Complex answers of cube root of 1)​

Answer 1

Answer:

1.2)

The fact that (1.1) can have, for α1,α2<0, solutions with Reλ>0 therefore leads to the dictum that delayed negative feedback can lead to oscillatory instability.
