Hi

On Q2 part C (attached), I'm at a bit of a loss on how to apply the Euler's Method. For the differential equations I have

V(capacitor): 100V_{c}+dV_{c}/dt+0.002d^{2}V_{c}/dt^{2}=0. As this is a 2nd ODE I have made dVc/dt=z so d^{2}V_{c}/dt^{2}=z, but now I'm not sure what to do. My timestep is 0.0002

Thanks for your help
