Op Amp Circuit -- Simple non-inverting circuit question

Homework Statement



Image


2. The attempt at a solution

0V*(236k/R1) + (-0.1cos(500t)*(236k/1k)) = 23.7cos(500t)

Is this the correct setup of the equation because there is no R1 variable to solve for...?

I am not understanding your equations. KCL equations are in the form of currents leaving a node, so voltages divided by resistances...
