Anybody remember their calculus?

So I missed a class or two in Calc and I've got an assignment due at midnight tonight.
Here's a problem i don't even know how to approach.

Five shrooms to anyone that can help me pull my head out of my ass.

Nope, I don't think you can use t, and x^4/4 doesn't work either.

I know the fundamental theorem of calculus is involved, we're working with the derivative of an integral.
I just wish I understood exactly how this works.
EDIT: Okay, I just beat down the problem after this. I still have no idea how to go about it if the x is the lower limit.

AHA!
You can reverse the limits by putting a negative in front,
then subbing that bitch out yields -x^3
Fuck y'all, no shrooms.

f(x) = 94/4 - x4/4
f'(x) = -x3
You could do it that way, too

First integrate with respect to t, then differentiate with respect to x. What do you get??

This is a prime example of The Fundamental Theorem of Calculus.

the only reason I made it thru Calc 1 is due to the tutoring by girl whom I was dating at the time. She graduated with a degree in mathematics and went on to get a teaching degree. I barely passed the class and did not retain a damn bit of it. (I also changed my major and didn't need any more calc)

Yeah you got it Skydog. I wasn't implying you got it wrong. Just putting in my two cents.

Well, I managed to use Maple to get 19/20 on this problem set.
I haven't learned anything, I'm still totally boned for the quiz tomorrow.
Also, I hope she doesn't look at this too closely.
Oh well.
Gonna get points, at least.
Skydog: I think we were expected to use some kind of substitution, but your explanation makes sense.
I think i'm gonna spend the next two hours studying, see if I can get any of this into my skull a little firmer.

I was the same way. Our prof would never tell us what anything was for, or what it did, and I would stay after every day, and bug him until he told me what we were doing. How hard is it to say, "A derivative is a line that tells you the slope of a function at any given point." Seriously. When we got to integrals, I said, fuck it. I'm just doing this so grad schools will not throw out my app. A C+ in calc is good enough for me.
