Typo on worksheet last page:

Column name should be : [A]_0; [B]_0; [C]_0.

You are right it's a typo.

c = 0.

Re: Week 9 Worksheet (2E,I,K)

Hello! When I plug in the same formulas and do all the same steps, I get a couple numbers off. For example, for 1d I got -75740.725. Is this a rounding issue or is something off in my settings. I don't think I rounded anything until the end.
Further for 1c I got .169V instead of .157V

Re: Week 9 Worksheet (2E,I,K)

I think this may be due to you using log instead of ln? On the equations sheet for the nearest equation they use ln. Which should we use?

Hi Elle,

You can use both. Please be aware that the difference is 0.0592 for log and 0.0257 for ln. If you plug in the number into two equations (in attachment), you will get same answer.

Hope this helps.
