MATH 2421-001 -- Calculus III
Summer 2006 Semester
DPGraph Section 11.6
- Problem #11: graph3d( r
<= z & z <= sqrt(8 - r^2)
)
The region above the upper cone is cut off by the sphere of radius
sqrt(8).
- Problem #14: graph3d( 0
<= z & z <= 4 - r^2 & 0 <= theta & theta <=
pi/2 )
Instead, you could designate 0 <= x & 0 <= y to
obtain Octant I.
- Problem #16: graph3d( r^2
- 4 <= z & z <= -r^2 )
Note that the xy-plane is *above* this solid.
