If anyone is any good with Calculus, can you please help me with this problem...

Find the volume of the solid generated by y=sqrt(x) bounded by the graphs of the equations y=0, and x=4.

I know how to integrate and do all this, but I keep getting a different answer than the books...

The correct answer is 128pi/5.

I get 256pi/15.

I really did used to know how to do these really quickly...too bad I can't find my notes, because I almost remember how to do it.

I struggled through calculus in my undergrad days - have never used it since.
I recommend a software package called Mathcad. It came out after I finished naturally. You can't use it on tests of course but it can help you check your work. Very GUI, and will plot your answers.
Most colleges offer a student discount. Worth the money IMO.

Hey--Mathcad--one of my favorites! Of course, you do have to know how to do the problems, but it makes checking answers (especially if there's a lot of different units involved) much easier and quick. Also can do plots pretty easily.

lol....I never even took calculus....hate them f'in classes. I think the highest math I took was like algerbra or geometery.. GOOD LUCK MAN!!!

Like most things that you learn in school. It depends on where your life and your career takes you that determines what education you decide is "valuable" or not.
For me, even though I don't use calculus per se, the challenge of problem solving is an education in itself.

? Something's missing from the question. y= sqrt(X) doesn't describe a solid, no?
