We have to use Integrals, and it's First year calculus course

if you don't mind can you show me the vectors way as well - Feb 25th 2009, 07:13 PMJhevon

Yah I have, I just don't get how to integrate with the equation's like from what to what

I know I should be using the intersects but there's 3 intersects and I think I only need to use 2 of them - Feb 25th 2009, 07:27 PMJhevon

Yah see I knew I had to do 2 integrals

how did you know it had to be from 0,2 and 2,5 - Feb 25th 2009, 07:37 PMJhevon
recall that we find area of a bounded region by integrating the top function minus the bottom function. f(x) is always on top, but g(x) is the bottom function between x = 0 and x = 2. similarly, h(x) is the bottom function from 2 to 5. the points we were given are our guides.
