Homework Statement
Differentiate the following with respect to x
y = [itex]\frac{4}{x^{3}}[/itex] + [itex]\frac{x^{3}}{4}[/itex]
The Attempt at a Solution
So the problem here is really getting this into a form that is easy to differentiate and i'd just like to show what I'm doing before I go ahead and do the rest of my questions. The step I'm least confident with is applying chain rule to each term separately...
I want to use the chain rule here, so I would rearrange to this;
y = (x3)-4 + (4)-x3
dy/dx = -4(x3)-53x2 - x3(4)-x3-1.0
dy/dx = -4(x3)-53x2
dy/dx = -12x2(x3)-5
(made irrelevant by discussion below)
So, is this ok? I am concerned that my second term disappears, but that's what it looks like I have to do.
Thanks for any help you can give!
