# Thread: Chain rule: Partial Differentiation at a given value

1. ## Chain rule: Partial Differentiation at a given value

I have this really gnarly chain rule question that I cannot seem to conquer.. I'm gonna try and post a screen shot of the problem rather than type it all out. Any input would be appreciated!

I cannot read your screenshot - too low resolution!!

The screenshot isn't working. To learn how to type math as text, please try here. For instance, the following:

. . . . .$f(x)\, =\, \left(\dfrac{x\, +\, 2}{e^{3x}}\right)^2$

...could be typeset as:

. . . . .f(x) = [(x + 2) / (e^(3x))]^2

When you reply, please include a clear listing of your thoughts and efforts so far, so we can see where you're getting stuck. Thank you!
