Hi, it is the pre-lab working. Please help me do that, i will rate up immediately whenever i have the answer. Thanks so much in advance.

a) Derive an expression for vout in terms of Rs, Rf, and Vin in Fig. 2 Rf R N 2 6 3 + Vout in Fig. 2. The non-inverting amplifier configuration b) Calculate Vout when Rs = 2. 2 kQ, Rf= 1 kQ, and Vin = 5 V. Determine the closed-loop gain Av. c) Repeat step 2 with a 1 ko resistor connected from the output of the op-amp at Vout to the reference node. d) Remove the 1 ko in Step 3, and repeat step 2 this time with Rf = 8.2 k
