Hi all,

How can I plot, say, y1=x+4, 0<x<5 and y2=2x+1, 0<x<10 on the same plot area?

Thank you,

Ozgur

I want to construct a sequence of diffenrential equations with

seq(diff(f[i],x)=k[i]*f[i],i=1..4);

but I get

0 = k[1]*f[1], 0 = k[2]*f[2], 0 = k[3]*f[3], 0 = k[4]*f[4] 

Is there anyone can tell me what I have done wrong? Thanks a ton!! 

This is my situation, please help me.

Hi,

How to load Maple-NAG connector to execut this example ?

Is it an additional program to install ?

Hello,

I was wondering if someone could assist me with the code for listcontplot.

I've tried the following:

M:=Student[LinearAlgebra]:-RandomMatrix(4,4);

listcontplot(M);

But this does not work.  Is there any way to use listcontplot, listcontplot3d, or any other command to generate something similar to what Excel calls a Surface - contourplot?

Thanks.

I see how to get the solutions of the Schroginger eqn

I have the function r=sqrt(1+(cos(2*theta)) and theta E [0,pi/2] I need to find the arc length of this function using maple 14

so far i have this

with vector (calculus):

ArcLength(sqrt(1+cos(2*theta)), theta=0..pi/2)

I dont know what to do after this

"I" is reserved for square root of -1.  I don't use complex numbers and want to use "I" in my equations.  How do I go about doing this?  I tried to unprotect it with a number of variations of quoting "I".

I'm using document mode with Maple 13 on Apple.

Thanks for your help.

My question is how do i get Maple to simplify every calculation that involves units automatically, right now i have to do this manually for every single one.

For example: This values all come from variables wich have units assigned to them.

Then i hit right click, Units -> Simplify and i get this:

I am using dsolve(..., type = series) to solve differential equations in the form of a power series. I plot these power series with different orders to observe how they converge. I use quite large orders (25 or even 50), and generating these solutions is slow.

I would like to generate power series with order 25, for example, and then truncate it to order 24 directly, instead of having to call dsolve a second time. I was hoping this could be done somehow using convert...

Hi All! I need your help.

I use the Student:-LinearAlgebra:-LynearSystemPlotTutor() and i can print it with:
print(Student:-LinearAlgebra:-LinearSystemPlotTutor);
then i got the: 
module () 
local ModuleApply, LinearSystemPlotMaplet, PlotOptionsWrapper, UpdateDisplay, NewMatrix, the_plot, sysML, helpStr, linSysMaplet, M, axisLengthInfo, axisLabelInfo, axisType, axisScaling, plotOptionsReturn; 
end module

If i would print the local...

If you type 1/1e6; then you get 0.000001000000000.

If you type 1/1e7; you will get

Hello,

I'm under pressure to complete the following plot for a Masters project. I just can't seem to find where the errors are. I'd be very grateful if anyone can help.

x_*,y_*,z_* are independent variables 

r_*(x_*,y_*,z_*):=(x_*²+y_*²+z_*²)^0.5:

r(x_*,y_*,z_*,t):=  (r
