Why does this part make sense to you?
(x^2+1+3x-5)
You're upside down. (Note: This is a common diagnosis when the sign is wrong but the magnitude is good.)
Try: (5-3x)-(x^2+1)
It's much more difficult with washers or disks. Give it a try!
Hello all.
Region bounded by...
y= x^2 + 1
y = -3x + 5
between x = 0 and x = 1
when rotated around x = 8
I got a wierd answer like -100, I know this is wrong and I'm confused.
my calculator equation was 2(Pi)fnInt((8-x)(x^2+1+3x-5),x,0,1)dx
Any help is very appreciated
