Hello again! I have to finish a home test for tomorrow (4pm). Im struggling basically with #2, #5 and #6. Why? because my professor is really old. just so you get an idea, she was the FIRST lady to graduate from EE from University Of Puerto Rico Mayaguez (no bull). She barely can walk or stand up. So what happend is that she got sick and after a month of no class she reappear with this home test. I will APPRECIATE GREATLY if anyone can help me answer the test. I will keep posting what I do so you can verify if what im doing is correct. Already did #3 and doing right now #4. Thanks for any help!!!
