    Derive a formula for Alpha dc gain in terms of Beta dc gain I have been shown several times by different people but it I still can't remember the teacher erases it so I start with Adc=IC/IE and Bdc=IC/IB and I must combine the 2 to come up with Adc=B/B+1? Help and do it slowly without eliminating a step
