I know what a force-extension graph looks like. DOes a force-compression graph look the same just with different axis? (compression on the x-axis NOT extension) DOes a compressive-strain graph (Young Modulus) look the same as a tensile stress-strain graph? if not what do they look like...

hey, I am not too great at physics, and i know this is going to seem like a relatively elementary question. when in class we learned about graphs, i never fully grasped the concepts of v(t), v(x), and v(a) graphs, such as how they all correlate to each other, and forming them. I am worried that...

[b]1. Prove that a graph with n vertices that has no triangles has at most (n^2)/4 edges. [b]2. [b]3. Um so i was thinking maybe you start off with a complete graph and then keep deleting edges so as to remove the triangles within it or something? Or maybe by induction?

Trajectory Graphs?? Homework Statement The trouble I'm having is with determining what information I can get from a trajectory graph and how that information differs from what I can find on a position vs. time graph. Is the acceleration I find just the rate of change in the direction of...

So it is my understanding from my book that the information that we can get from a trajectory graph is the direction of velocity, but not the magnitude of velocity. If the tangent line to a point on a trajectory graph just gives the direction of velocity, why can the trajectory graph still be...

Hi all, If I have to prove that the graph G and its complement G' are isomorphic, then is it enough to prove that both G and G' will have the same number of edges. Intuitively its clear to me, but how do I prove this. If there's a counterexample, please post. Thanks in advance.

Hi Guys, I messed up bad on a recent quiz on these easy VT and DT graphs. I am having trouble going from one to another. I recently took this quiz and pretty much got everyone wrong since then I have googled and read the chapter as much as possible, but I can't find any good completed examples...

Alright let's says for example we were to sketch y=(x-2)(x-3). You would find x intercepts and you would write it as x-2=0 OR x-3=0, thus x=2 OR x=3. Why do we use the word OR when we use both of the intercepts to sketch the graph anyway? Why cannot we use AND instead.

find the exact area between y=ex, y=2, and the y axis im not looking for a solution, just hints on how to get started. would i just go ahead and integrate the function from 0 to 2 or would i solve the function for x and then integrate or are those 2 idea just completely wrong? thanks

In general, if f(x)=k but only for a < x < b and c < x < d how would you integrate the graph ? To find the mean for example, would you find the mean for each and add together, or is there some special thing for this case?
