At a total loss here

Ohh ok I got it now. Thank you so much for bearing with me.

Like, wouldn't I differentiate the entire function in terms of x?

I think my confusion lies in splitting the function into two parts. So for the first part of the function differentiating wrt x gives 0 but that's not the case for the second part of the function. Why do I ignore that second part for x?

But we haven't taken the partial derivative wrt y. Don't you have to go in order taking the partial derivative of x, y, then z?

So for the second term, differentiating to z is 0 as well

So that differentiates to 0 then

Isn't that what you would get if you differentiate with respect to x?

I did take the other variables as constant. I'm saying that by keeping everything constant but x, the x term differentiates to 1 if you look at the function.

So I split the function like you said and I got xln(y100+37z11 / xz rad(y2+1 and when I take the partial derivative of that term wrt x, x is no longer in that term

So if I take the partial derivative wrt x and the result has no x term what does that mean?

This is my work:

Homework Statement I know I would use the curvature equation |f''| / [1-(f')^2]^3/2 and then take the limit of that to -1. I just don't understand why I have to take the limit of the curvature and when I take the limit of the curvature I get |-1| / (13)^3/2 when the answer should be 2.

Homework Statement So I know I have to take the derivative with respect to x, then respect to y, then respect to z, but I am not getting the right answer. I know that the answer is 0 and my professor did it with very few steps that I do not understand. Can someone please guide me through it?

Using that then, I do V = (12V)(40 ohms) / (70 ohms + 40 ohms) = 4.36 V and that doesn't appear right
