Green's Theorem problem
∫c (x^2+y^2)dx + (x^2+y^2)dy , C is defined by y=x , y=(1/6)x^2 , 0<x<6
For the limits I'm doing dydx, so:
y is from 0 to x
x is from 0 to 6
∫c (x^2+y^2)dx + (x^2+y^2)dy
= ∫∫2x-2y dydx = 2xy-y^2 from 0 to x
= ∫x^2 dx = (1/3)x^3 from 0 to 6 = 72.

Last two intergrals and I'm done for today's homework.

Also I got one intergral down to 1/u du, and is 1/u the same as ln|u|??

How do you factor X^3+5x^2-28x-32?
pls help
• math - Reiny, Thursday, July 5, 2012 at 6:24pm

on the second try, I found f(-1) = 0
so x+1) is a factor
