1. The problem statement, all variables and given/known data Find the volume of the wedge-shaped region contained in the cylinder x^2+y^2=9 bounded by the plane z=x and below by the xy plane 2. Relevant equations 3. The attempt at a solution So it seems a common theme for me I have a hard time finding the limits of integration for the dθ term when I integrate in polar coordinates. For this integral I am setting it up triple integral rdzdrdθ where dr is between 0 and 3, dz is between 0 and rcosθ and dθ is between 0 and 2∏? is that correct?
