math majors or someone good at calc

whats the difference between the disk and washer method and how exactly would i use them

like the dish washer is where you put the dishes in and then put the soap and then wash and they unload the dishes and then put them in the cabinets but if its a big pot and pan you gotta wash them by hand and skip the dishwasher and leave them out to dry overnight so yeah

calc 2 :droool:

What the fuck is the disk and washer method

na education...

depends on which ones easier, like is the graph y in terms of x, or x in terms of y. They are pretty interchangeable though because they are pretty much the same thing

9-4=5

Disk Method: easy
When to Use: For solids that have circular cross-sections and no hole in the middle.
Function Needed: One function f(x) or f(y) to define the curve.
Integral Formula: V = π ∫ from a to b (f(x)^2 dx or (or y)

Washer Method: (basically the outer hole - the inner hole)
When to Use: For solids that have circular cross-sections but have a hole in the middle.
Functions Needed: Two functions f(x) AND g(x) or y equivalent, to define the outer and inner curves.
Integral Formula: . π ∫ a to b f(x)^2 -g(x)^2 dx ( or y)

bro ask GPT arent you people young and tech savvy.

disk and washer are very very similar, but usually you just use washer for functions that have a hole in the middle of the function that would require 2 integrals if using disk
disk is pi int of f(x)^2 (or y) dx (or dy)
washer is pi int of (outer function^2 - inner function^2) dx (or dy)

i took calc ab last year and got 5 on the exam but i forgot 😂😂😂
