Hi All,

The phase margin is given by the relation below.
Who can demonstrate how we found T1 and T2 ?



I calculated secΦp and tanΦp like shown but I couldnt find the result as it is provided.
 

try taking tan of the first equation an then use the law of the tan(A+B)
i think it will be solve that way.
