So when analyzing the circuit, one of the transistors BE voltage has to be .7 and the other has to be less than .7? If Vbe is greater than .7 then it would be wrong? Also when doing these diff bjt, is it always one transistor on and one off? or can it have both transistors on?

I'm trying to understand the differential mode for a BJT. For the second picture, when we apply +1V to the base of Q1 and 0V to the base of Q2. Why is the emitter voltage .3V instead of -.7V? Similarity, for the third picture, why is the emitter voltage -.7V instead of 1.7V? Thanks for the help!

After reading all the comments, I understand it now! Thanks to all who replied!

I have a general question regarding eigenvalues/vectors. Say you are working on a matrix [ 1, 1; 4, 1] and you find the eigenvalues to be 3 and -1. Does it matter which eigenvalue is first...meaning does it matter when it is λ1= 3 and λ2=-1 or the other way around? When you write out the...
