so I understand the basic premise of differentiating a first ODE, or I thought I did. I have the equation y'-y=abs(x-1). I have no idea of how to go about this. Can someone walk me through how to do this? I'm attempting to study for a test and this is one of the practice questions he gave us so...

okay so 1. do i need to evaluate in cylindrical coords even? 2. am I using my elliptic hyperboloid equation for the integration? 3. it would be a double integral of that elliptic hyperboloid equation or no? I'm sorry. I'm very confused now.

But there is no plane z=0. It's-h/2 and h/2.

i got the triple integral with limits stated above and of r^3 -rz^2 drd(theta)dz..I made my last integrand be from 0 to a..is this correct? I then integrated it all out and ended up with [pi(a^4)h]/2. Is this right?? Could I have possibly solved this?

For positive a and h, let A designate the region of R3 enclosed by the elliptic hyperboloid, x2 +y2 -z2 =a2 and the two planes, z= -h/2 and z=h/2. Determine the volume of A So I figure this will be a triple integral in cylindrical coordinates. the first integrand being from -h/2 to h/2...
