WebMay 15, 2011 · 256. hi flyingpig! zero divergence means that the amount going into a region equals the amount coming out. in other words, nothing is lost. so for example the divergence of the density of a fluid is (usually) zero because you can't (unless there's a "source" or "sink") create (or destroy) mass. the electric field is like a fluid, and the field ... WebSep 3, 2024 · 3. I like Serena said: Hi PrathameshR ;) There is no real mathematical distinction. Identical zero is merely an emphasis to indicate it's 'more' zero than might otherwise be thought. When we say that a function is identical to zero, we want to emphasize that we really mean the zero-function, which is zero everywhere in its domain. WebOct 31, 2015 · In a linear relationship, the variables move in the same direction at a constant rate. This means if we have non-monotone related variables we can observe a zero correlation even though they are not independent. To illustrate this say for example we have a f ( x) = x 2, using python to evaluate the function. dr. jonathan marsh indianapolis
