### Basic (algebra) 2-D plotting in Maple...

July 21 2014

Hi all.

I'm a student learning Algebra.

I've been searching everywhere and cannot work out how to plot and analyze a function graphically in Maple.

For example, you can see in this video, There is a point for the Vertex of a parabola on the example

http://www.maplesoft.com/TeacherResource/topic.aspx?m=1&c=1&cha=3&sec=9&top=31

I would like to put things like this on my graph (Vertex, or X-Intercepts, or the intersection of 2 lines)

I can certainly find this information by using Algebra (vertex form, etc) but it would help my understanding to also visualize the functions graphically.

### weight matrix of graph...

July 15 2014

suppose W1 is weight matrix of graph G1 and W2 is weight matrix of graph G2 (G1 and G2 has same vertices and same edges but with different edge weights)

we want to create graph G3 that has a weight matrix W3. suppose w3[i][j] is an element of W3. we must have :

w3[i][j]=max(w1[i][j],w2[i][j])

w1[i][j] and w2[i][j] are elements of W1 and W2,respectively.

how can we create such graph G3 ?

### paths in graph ...

Hi i have two questions about paths in graph package: 1. suppose we have: path1=[1,3,5,7,9] path2=[1,2,3,6,7,8,9] if we want to create a graph that it's edges are edges of path1 and edges of path2,how can we do this? edge set of our graph should be {[1,3],[3,5],[5,7],[7,9],[1,2],[2,3],[3,6],[6,7],[7,8],[8,9]} 2. suppose p is an arbitrary path on a given weighted graph G how can i calculate weight of p (that is sum of it's edges weights) in maple ? thanks very much for your help

### 2 question about graphs in maple...

July 11 2014
3 8

i have 2 questions:

Question 1. suppose we have generated a random weighted graph with 100 vertices and 2300 edges and found shortest path frome node 1 to node 100 using function ShortestPath(G,1,100). this function returns a path like [1 3 8 2 9 100] but don't get us value of shortest path!

in other words if weights are costs of travelling on edges,we want to find minimum cost of travelling from node 1 to node 100.

how can i find value of shortest path (minimum weight/cost) ?

Question 2. i want to create a sub graph of G by removing the edge that has maximum weight on shortest path found in Question 1. how can i find such edge and how to create such sub graph?

thanks

i am using plot command to plot the first vs the second column in the attached file A.txt

it is giving a strange plot. while plotting the first vs second column in kgraph i am getting the correct plot

why is maple giving me a wrong plot

you can find the two plots and the raw data file A.txt

### Volume of a Solid of Revolution: Rotation about an...

Hello everybody, i need to graphic a couple of functions just like this one:

http://temasmatematicos.uniandes.edu.co/Casquetes_cilindricos/Pags/Anim_1.htm

i have been watching this:

http://www.maplesoft.com/teachingconcepts/detail.aspx?cid=12 VISUALIZATION --> Animation 2

i've tried with (plots) (plottools) animate, etc. but i can't figure out how to do it.

It would be very helpful if someone explain me how to do this.

Thank you all!

### Implementing Rodrigues' Rotation Formula...

May 12 2014

I'm trying to use Rodrigues' Rotation Formula to graph a circle--by rotating a point, naturally--and I'm not sure how to implement that in Maple. For something like a function, allowing a variable--say, x--to vary and produce a curve is natural, but the evalm() function doesn't handle that very well: I can use the formula to *evaluate* the rotations, but not to use them to graph the circle.

I looked for something like solids of revolution--after all, I'm doing something pretty similar--but didn't find anything helpful; apparently there's a way to make solids of revolution, but it's pretty specific and would be difficult to adapt?

How do I plot the graph of 3 functions into one page (that is, as a series). Thank you.

Please this is urgent! I can't seem to be able to upload my job on here.

Thanks.

Hi,

m := Matrix(8, 2, [1, 2, 1, 4, 4,1,4,7,1, 2,4,1,1,4,4,7]);
plot(m)

I would like to add a mame of each point in the graph as: alpha:=(1,2), beta:=(1,4) , gamma:=(4,1),eta:=(4,7)

and the symbol of each point is a bleu sphere.

and how to remove axis borders, tick marks.

### Spacecurve command does not work...

Hi

I'm using Maple 17 on Windows 8 (64-bit).

I have noticed that when I use the 'spacecurve' command and try to display it with the 'display' command, nothing shows up. I made sure that I used 'with(plots)' and 'with(plottools)', still nothing. However 'plot3d' works fine. I think it has something to do with the version of Java I'm using but I don't know what. Any help is welcome, thx
