Consider the ideal noninverting op-amp circuit in Figure P9.45.

(a) Derive the expression for \(v_{O}\) as a function of \(v_{I 1}\) and \(v_{I 2}\).

(b) Find \(v_{O}\) for \(v_{I 1}=0.2 \mathrm{~V}\) and \(v_{I 2}=0.3 \mathrm{~V}\).

(c) Find \(v_{0}\) for \(v_{I 1}=+0.25 \mathrm{~V}\) and \(v_{I 2}=\) \(-0.40 \mathrm{~V}\).
