hard stuff man

can help for fg.

Post your problem ?

i need like concepts on weird disk and washer finding the volume of the shape using integral stuff. isnt there like a complete concept somewhere? tried youtube too many vids.


like they draw this shape on the map then flip it to x or y axis, then find the volume, most of the time they find radius and use the area to integrate, pretty weird.

need to use washer and shell method which involves taking double integrals. i'll help for fg pm me.

there are formulas for the disk and washer method. pm me if you need them i got them in my calc ebook. i was never good at applying them either, it was always tough for me to identify the upper/lower indexes for the integral & trying to determine the radius. shit gets even more tough afterwards with fluid pressure imo

they are so random tho, idk which ones to use ever, squares, semicircle, weird bases, and weirds shapes combinations.
