Question

someone who's good at partial differentiation???

Answer 1

what is your question?

Answer 2

was that your solution?

Answer 3

Yes :)

Answer 4

I think the error my teacher talked about lays in the solution. He said it was a minor error but it was important that I corrected it

Answer 5

You there?

Answer 6

ya sorry I am trying to remember my Calc. I am trying to see where the small mistake is. it could even be the notation, I'll be right back

Answer 7

That's all right! Thank you :)

Answer 8

I think it really is just notation. I'm almost done with the problem but I am seeing similarities

Answer 9

What happened with your \[\delta _{y}/\delta _{x}\]

Answer 10

or was that just a typo?

Answer 11

I don't know? Maybe that's the error?

Answer 12

Honestly your work looks wonderful. I am not really sure I can find an error, but I can't figure out where that came from, or went. because i didn't think we were taking any derivatives of y were we? and the only other thing that I would suggest was that when you have parts of the equation that just have z or just have x i believe that you only have that partial there. (that probably didn't make sense, but if you have \[(z+1)^{3}y\] wouldn't you only have \[\delta/\delta _{z}(3(z+1)^2y)\]. that last part may be entirely wrong. I hope I didn't waste your time

Answer 13

No, not at all :) Thank you! I will try looking more into it

Answer 14

Good luck :)
