I am having difficulty trying to figure out how to solve this circuit using the trapezoidal rule. I know how to do so in a first and second order RLC circuit however this particular circuit is giving me trouble. If anybody has any tips that would be greatly appreciated. Thanks.

Here is the first problem: enter image description here

Here is the code for the first problem: enter image description here

Here are the notes for nodal method. This is what I don't know how to implement. enter image description here

  • \$\begingroup\$ Can you give more information on how the other exercises are solved (the steps required)? I'm mainly interested in how you build your matrices. \$\endgroup\$ – Sven B Feb 28 '19 at 8:26
  • \$\begingroup\$ The previous problem was just an RL circuit. I edited the questions and included the first problem with my solution. @SvenB \$\endgroup\$ – Timothy Beacham Feb 28 '19 at 22:17
  • \$\begingroup\$ The solution you provided for the first problem does not include anything about time discretization/trapezoidal rule for question (b). Have you seen anything about (Modified) Nodal Analysis? \$\endgroup\$ – Sven B Mar 1 '19 at 6:50
  • \$\begingroup\$ Updated again to includes nodal notes @SvenB \$\endgroup\$ – Timothy Beacham Mar 1 '19 at 14:56
  • \$\begingroup\$ And what do you have problems with in this problem that you didn't have in your previous exercise? Your question seems to be quite vague. \$\endgroup\$ – Sven B Mar 2 '19 at 0:33
