Notes
- If the integral is setup in polar coordinates, the integrand is divided by $r$ for 3D plots over $xy$-plane.
- "Explosion" mode may look a bit weird for the $xy$-plane and $d\theta\, dr$ order of integration: think about why it is difficult to draw!
Basic Troubleshooting
- If the input areas "grey out", try reloading the page (this will reset all input boxes to their default values).
- If nothing works at all: try a different browser (Mozilla Firefox is known to work well), try again at a later time.
