So I need to find a vector v with these properties 1. magnitude of 10 2. angle of 45° with positive x-axis 3. angle of 75° with positive y-axis 4. positive k component. I understand basically just that the k component has to be positive. Any help would be appreciated.

Homework Statement For calc 2 we have to write a formula using integration that will find the volume of any tree log that is cut. Using the picture that is attacked I came up with this equation. The integral from 0 to h of pi*(((R-r/h)x+r))^2)dx. Any ideas about my formula or anything would...

So I have this homework problem : "A radiation detector is a circular disk which registers photons which hit it. The probability that a photon hitting the disk at a distance r from the center is actually detected is given by S(r). A radiation detector of radius R is bombarded by constant...

Also if I flipped the frustum over, so that the height of the frustum is laying on the x-axis, I can just integrate it over the x-axis right?

hah yeah I meant Angel Food Cake*

For class I had to measure an angle food cake pan using integration. The pan itself had a circular hole in the middle of it. So I figured I would take find the volume of the Large pan and then subtract the volume of the Small circular hole in the middle. As far as integration goes, I am kind...
