I am afraid to say that your topic has been closed due to our policy. Please understand that DNH is not a platform to do your homework for you.
It would be considered better for your future career if you can:
- Read your textbook through-fully.
- Attempt to solve the homework.
- If you cannot solve that, list out all your problem, and try to analyze one by one.
- If you’re still stuck on any problem, come back here and ask us about that specific problem.
