If alphaand betaare different complex n...

If `alpha`and `beta`are different complex numbers with `|beta|=1,`then find `|(beta-alpha)/(1- baralphabeta)|`.

Text Solution

Verified by Experts

Given,
`|beta|=1` and `|[(beta-alpha)/(1-bar(alpha beta)]|`
We know that, `|Z|=Z bar(Z)`
`(beta-alpha)/(1-bar(alpha beta) [bar((beta-alpha)/(1-bar(alpha beta))]`
