## Inquiry

To see if I understand this correctly, if ${\displaystyle T(x,y,z)=10^{-(x^{2}+y^{2}+z^{2})}}$, where T is conceived to be the temperature in a room as a function of the room's 3-dimensional co-ordinates (with the origin as a "heat source"), would T be a radial function? —Anonymous DissidentTalk 14:41, 30 November 2009 (UTC)

Yes, it would be. In fact, any Gaussian distribution centered at the origin would be: and these all effectively model the heat in a room with a point heat source at the origin. These are actually a pretty important example of radial functions. Sławomir Biały (talk) 14:46, 30 November 2009 (UTC)
Do you think it might be worth mentioning in the article (not my example specifically, but the point about Gaussian distributions)? —Anonymous DissidentTalk 14:51, 30 November 2009 (UTC)
At some point, yes. Sławomir Biały (talk) 14:52, 30 November 2009 (UTC)
