Hello, I am having difficulty with this particular problem involving a BJT circuit. I was able to solve all other BJT problems except for this one. The teacher does give the solutions in hints, but I would like to understand why it is solved this way. Here is the problem: I wrote all the KVL equations... so KVL for base-emitter, KVL for base-collector and KVL for emitter-collector. I also know all the formulas like IE = IB + IC, IC = B*IB, IC = A * IE, etc. My problem is with the R1 and R2 resistances. If one them was grounded I would not have any trouble, but since they are, I do not know how to proceed or what simplifications to be made. Thanks again !
