I’m taking Calc1 over the summer which, as a 5-credit class, is particularly brutal. I’m in class 14 hours/week and doing at least twice that in homework plus a husband and kids. Let’s not talk about how insane I am, please.

Here’s the issue: I got an 82% on my first test. My second, 65% (I’ve had straight As thus far, so this is killing me). The prof allows us to “fix” one test for half of the remaining points so if I get everything correct on this fix, I can bring it up to an 82, which is huge.

I’ve finished every other error but, I’m stuck on one problem and I need some help. It’s regarding the chain rule of derivatives. Here is the problem:

Let f, g and h be differentiable functions. Find:

[f ° g (x) + x^3h^2(x)]

My answer is currently this:

[fʹg(x) * gʹ(x)] + [3x^2h^2(x) * x^32h(x) * hʹ(x)]

Is that even close to correct? Please help!
