Does anyone know of a very good website that can teach me to better understand the disk, washer, shell method to finding volume of irregular figures (solid of revolution)using of course, integration techniques (such as when to recognize integration with respect to y or X for the axis of revolution)?

No, I don't know of one on the web. But I can recommend a book readily available at the college bookstore, or your local Barnes Noble (or online At amazon). I recommend look at it before buying.

Schaums Outline Series: Calculus series. About 17 dollars. Look at them, and pick the one you need. Very good.
