3. anonymous

yep, part 7, b and d ;)

4. anonymous

okay you there...here we go.

5. anonymous

rewrite the fraction taking the square root to the top and write it in exponential form...

7. anonymous

Now we will use the product rule and chain rule. Remember all terms are constants except for the v's...

10. anonymous

remember m0 is a constant...

11. anonymous

that is it for 7b.

12. anonymous

give me a minute and i'll look at d.

13. anonymous

are you ready for 7 d?

finished....any questions?

22. anonymous

Nope! Thanks a lot again :) Really elucidative. What bothers me is that I can't master this faster way of performing the chain rule, and then I try to name some variables to apply the slow and steady method, which results in further confusion... I'm gonna watch the video lecture again I guess... But I got your method really easily, thanks again!
