hi! Does anybody know, is there a way to show 3d directed graphs, where vertices are given with coordinates? tnx for help

I have recently been working in Mathematica 6.0 trying to graph various curves using ParametricPlot3D. I have specifically defined: a1[p_]={(sqrt(25-p^2))*Sin[10*p],(Sqrt(25-p^2))*Cos[10*p],(p)^2}; Graphing this is no problem. The problem is I am trying to turn this into a Fernet type...

Envy of the 3D modeling abilities of Hans, I have tried mine. So, new thread for string related plots. In this post, you can see interacting strings. Really you can not guess if each vertex is a fermion or a boson in a superstring theory; I can not see how to tell it in pictorial way. So even...

basically I'm in the last 2 chapters of multi variable calculus (right now in double integrals) and i know how important it is in some exercises to sketch the 3-d graphs accuratley. However all the 3-d graphs that I'm trying to sketch are very off... even a simple shape like a cylinder looks...

Homework Statement If I’m to graph a plot of s (displacement) vs t^2 (time squared) then what would be the independent and dependent variable, t or s? I’m supposed to supposed to use this graph to find a slope with error bars and use the appropriate kinematics equation [which I think is s(t)...

In graphing functions, I don't get how adding a constant c to the x value in say y=f(x) moves the graph to the left. Surely, if you add a constant to x, its value increase and so the graph should move to the right?

Homework Statement I'm studying for a Calculus test and I am having trouble on a problem. And who better to ask than the members of physicsforums!? Basically, we are studying average acceleration, velocity, secant and tangent lines. We are given the graph of a function, and its...

1. I REALLY need help here! I've been doing pretty good in physics so far this year, but a new quiz devastated me. Here's the problem: I was given a Force vs. Time graph and a lot of the questions pertained to the mass of the object. How do I find the mass only given a F vs T graph? Homework...

Consider the graph of z=xy. Choose the section y=x, i.e. intersect the plane y=x with the graph z=xy, I get z=(x)(x)=x^2, with y=x. Now is this a parabola? (note that the curve actually lies on the plane y=x) If so, why? Also, is this parabola going to have exactly the same shape as the...

Homework Statement 1 = absolute value( (sin(x)-x)/(sin(x))) * 100 Homework Equations Don't think there are any. The Attempt at a Solution I decided to do it graphically, so i graphed y=.01 and y= absolute value(1-(x/sin(x)) I got x = .244 radians for the intersection and I am just...

If the original graph, f, has a cusp, obviously the derivative is not defined at the x-value of the cusp (resulting in an asymptote). but, what if you are viewing a graph of the derivative, f ', and it has a cusp.. what is going on at the x-value of the cusp on the original graph, f ?

I'm have a hard time with graphs equal to zero like these: A. x^{2}+y^{2}-4x+2y+5=0 B. xy=0 C. 2x^{2}-3y^{2}+8x+6y+5=0 I know how to simplify them: A. (x-2)^{2}+(y+1)^{2}=0 C. 2(x+2)^{2}-3(y-1)^{2}=0 However, I just can't seem to figure out there graphs. They seem so...

I have problem about constructing graphs. Comparing these two problems: 1) A hiker walks 27.0km from her base camp at 35 degrees south of east. The next day, she walks 41.0 km in a direction 65 degrees north of east. In my book, the graph is like the one that i show you here. but why 65...

I'm not following the format because this isn't really a homework question -- I'm just studying for my finals and encountered a few graphs in the electricity unit, and want a few things cleared up. So in a current-voltage graph, the slope is 1/R, and power (according to my teacher) is the...

Just a question. The internet is mixed with this. But in a Stress Strain Graph; after the YIELD POINT, does the material experience more strain for a lesser stress? I.e. does it slightly curve down before going up?

I'm having a lot of problems with this topic. I know what the sine, cosine and tan graphs look like. one question i come across fequently is "given that sin 30°, what is a) sin 150° b) sin 330°. - i can work it out on a calculator but the questions on a non-calc paper. I am presuming it's...

Homework Statement no specific question but generally they give you a graph of f(x) (with semicircles, lines, above/below x-axis - could be anything) and say that g(x) is the integral from 0 to x of f(x). then they will ask things like: 1) g(2) 2) find relative min/max for g(x)...

I'm just posting a random graph algorithm problem for discussion fodder, since another interesting graph algorithm post was removed due to a threatening-sounding title and lead-up. This is from Cormen, Leiserson, Rivest, & Stein, 22.4-3 (not a homework problem of any kind, just for fun--I had...

I was having some trouble with a problem. The problem reads: Sketch the graphs of y = x^2 and y = -x^2+6x-5, and sketch the two lines that are tangent to both graphs. Find equations of these lines. I've graphed the two parabolas and drew the tangent lines. I've found the derivatives of each...

There's a series of questions in my homework that I don't understand how to do. They give a graph of f ', then say, given f(-1)=-3/2, sketch the graph of f on the interval [-2,2]. (with different numbers each time, of course) How would I graph f?

i was wondering how you would find the amplitude, vertical translation, horizontal translation and the sinusoidal axis either from just an equation, like 1/2(y-7)=cos3(x-60), or from the graph if you are given one.

Reaction Time? how can you find reaction time from a velocity time graph? anyone knows i need an answer asap thanks a lot =).

I have my original graph f, and I want to make 2 other graphs out of it (each with their own transformations.) g(x)=2g(1/2x+1) so it gets stretched vertically by 2, stretched horizontally by 2, goes left 1 and up 1. But my problem is with h(x)=2[g((x+1)/2)+1)] What are the transformations...

hi! a ball is dropped from a height of 1 meter above the floor. Take the origin to be the point from which the ball is released. would the graph be like a curved graph rising to the right starting from the origin? how would the graph look like if a car is parked on a steep hill? thank you

Hi, I was thinking about the following and would like some clarification. Suppose that we have a continuous scalar function f:R^n \to R with a critical point at say x_0, where the dimension of x_0 depends on the value of n. Consider as an example f(x) = x (n = 1). The point x = 0 is a...

Can someone please tell me how to draw a VT graph from this DT graph? Thanks. Edit: Sorry, one more question. This is about unit conversions though. How do I convert 175 kg x m/h2 to g x cm/s2?

Can someone please explain to me how to draw a velocity-time graph from a distance-time graph? Are there any general rules about drawing a VT graph from DT graph? Thanks a lot.
