This seemed easy...at first
Can someone please help me with a problem?
I'm studying op-amps and can't quite figure this one out. It's analyzing a noninverting op-amp circuit to find the gain. You shouldn't need any electronic knowledge to figure this out - it's just algebra.
Vin = VoutR1/(R1 + R2)
gain = Vout/Vin = 1 + R2/R1
I cannot figure out, no matter what I try, how to get from the first equation to the second. Can someone please give me a step-by-step solution?
Attached is a copy of the entire text for context.
