Hello
Please look at my attempted solutions.
Thank you very much for your time.
Please look at my attempted solutions.
- For Question 2, are both of my solutions correct?
- For Question 3, what am I doing wrong? The official solution has two sets of answers. I have only one.
- For Question 4, my answer is very different from the actual answer. The difference arises only due to a sign change. What am I doing wrong?
Thank you very much for your time.
