ok so I'm on the last problem of my webassign and I cant figure it out (prob. b/c I left my notebook somewhere). Ok here it goes..

I found that the antiderivative of 3x^2 is x^3 + C now I am supposed to find the exact value of the area under the curve and I have no idea how...

can anyone help explain this to me please?
Thanks!!

this is a definite integral, yes?

4/10/2008 10:04:19 PM

yes

4/10/2008 10:11:34 PM

by using riemann sums

well, what are your upper and lower bounds?

4/10/2008 10:18:01 PM

^exactly.

It should be as follows:

[(upper bound)^3] - [(lower bound)^3]

(the C drops since you have values to plug in)

Just out of curiosity, we are towards the end of the semester and you don't know this?

she had another thread that went away with the server crash where she had tdub do probably 10 questions from a webassign that were very basic derivative problems.

i have the worst teacher ever, even my TA thinks that she is awful so I never know how to do the webassigns but once I figure them out I always make at least a B on my tests.

Ok well then at least the whole problem, including the bounds.

what calc is this?

that's easy stuff...

it makes much more sense now

ha, I'm glad I don't have to do this shit anymore cause I hardly remember any of it.

4/11/2008 1:43:26 PM

i'm not in poli sci anymore gah haha

com?

^^disagree.

I forgot, the title of it is "How it Works" and the rollover caption is

It's pi plus C, of course.

Well I could understand how it might be confusing if you have never taken any calculus before. When I was a freshman in 141 I think we started very basic polynomial integration about this time in the semester, and I had never had any type of calculus before.

sin x / n = six
