Im new to finding volume using the cylindicral shell method so what should i do. I know I will eventually plug equations into the integral 2piX(f(x)-g(x))dx x=y x+2y=3 and y=0 revolve about the x axis

Alright and I am also having trouble with finding points of intersection of y=6-x^2 and y=2 about the y axis

Homework Statement y=x-x^3 y=0 Must find intersection points by way of the x-axis Homework Equations The Attempt at a Solution I know you have to set them equal to each other i just do not know what to do from there.

Alright I am going to try and do it from here thanks so much for your help.

ok i have found the anti derivative of the numerator and now i must find the mass using the equation already mentioned. I am not given rao though I am only given the function f(x) so how do I go about finding the mass now. Sorry if I am asking dumb questions it just tells you how lost my teacher...

looks like it to me besides the fact that my teacher told me to put the integral you gave me over mass with mass being (Density)f(x)dx Do i even need to use the mass?

What my teacher told me was to use the mass total (M)x over mass to find the y coordinate. so y=(Density)(x)f(x)dx/(Density)f(x)dx Im not sure how to make the greek letter row on here so i just put density in parentheses

Hello, Here is my situational plea. My calculus teacher is horrible at teaching and god help me i have tried to get help in every position possible, so i am now hoping you guys can help me. I love calculus and I am sure i would i enjoy it more if i had a better teacher. The problem is I...
