Circuit link:

In Figure 1 of the above link (Basic Precision Halfwave Rectifier), how
would I analyse this circuit? At first, I thought R1 and R2 didn't
really do anything because it seemed like they weren't part of any
feedback networks, but when I ran a simulation without them, the
circuit did not rectify.
Any tips?
I initially analyzed the circuit by replacing the diode with a voltage
drop. I assumed 0.7V, so I wrote my output as Vout = Immediate voltage
output of opamp - 0.7 V. Then, set Vout equal to my Vin. That's why I
had the impression that R1 and R2 did not do anything.
Thanks!
