How to determine a hole in a graph? - Physics Forums
Jan 18, 2015 · I'm aware that in order to find the hole in a graph, you need to factor both the numerator and denominator, and look for terms that cancel out. However, is it merely just looking for a term that …
When is a function not differentiable? - Physics Forums
Apr 13, 2011 · The graph of f is identical to the graph of y = x + 3 except that the graph of f has a discontinuity (a hole) at the point (3, 6). This kind of discontinuity is called a removable discontinuity. …
Calculating Maximum Stress for Flat Bar w/Circular Hole
Aug 23, 2011 · trying yo figure this out: the graph of stress concentration factor K for flat bars with a circular hole geometries are shown in the diagram link below. a load of 50kN is applied to the plate. …
Why Graphing Tools doesn't represent hole in a graph
Dec 20, 2014 · Why Graphing Tools doesn't represent hole in a graph of a function. A Hole at a point in a graph is point where function is not defined.Suppose there is a function ##\\frac{x}{\\root{x-1}-1}## …
Basic (?) calc problem with flow out of a hole in a bucket
Oct 30, 2015 · The graph of that is a parabola opening downward with vertex at (0, H_0). As t increases, H decreases until H= 0 at which point, because there is no more water in the bucket, the whole …
Show that this graph isn't differentiable at x=1 - Physics Forums
Sep 19, 2018 · These different intervals do not approach the same rate of change, or derivative, as they approach the same x value. This implies a kink in the graph at x=1, which coincides with what I drew. …
Calculate Hole Depth: Stone-Drop Time Problem with Speed of Sound …
Sep 27, 2009 · Homework Statement A spelunker (cave explorer) drops a stone from rest into a hole. The speed of sound is 343 m/s in air, and the sound of the stone striking the bottom is heard 1.24 s …
Why are functions not differentiable at holes? - Physics Forums
Jul 31, 2013 · I understand at cusps, corners, etc, because the negative and positive directions do not agree with each other. But what about at jump discontinuity on a graph? Why wouldn't a function be …
Water flowing out of a tank through a hole • Physics Forums
Jan 28, 2020 · I assume the water to start flowing from rest at position 1, hence ##v_1 = 0##. Applying the continuity equation, ##A_1 v_1 = A_2 v_2##, we find the (wrong)...
Proving G Has Same Degree Vertices: Graph Theory - Physics Forums
Sep 19, 2011 · OK, you are on the right track, here. Do you know what the pigeon-hole-principle is? So, if a simple graph G has n-verticies, then what are the options for the degree of a vertex in G?
