how can i define an index for a vector?

for example i have

V:=Vector(5)

for i to 20 do
...
V[i]=..

od.

when i write V[i] i want to address it for  "i"'s number from the loop,not element "i" of the Vector. how can i define it ?!
thnx for help 

i have a problem in using command "collect". 

if i uninstall maple and keep some dll,  Is it possible to use openmaple without install maple?

What does convert(max(a,b), piecewise) algorithm use?

Hi All,

I am working on a soil mechanics problem that defines a Cam-Clay model via a system of ODE's and initial values. For this problem there are two parts, the elastic behaviour followed by plastic behaviour.

I have 7 ODE's all wrt to an independant variable called eq. I wish to run the elastic dsolve expresion in such a way that, at the value of eq where a dependant variable f(eq) = 0, I can extract all 7 of the parameters for use as initial...

Maple people:

Does anyone know why, if you plot a discontinuous function of one variable, Maple's default behavior is to try to make the function continuous by adding a vertical line segment?  I don't know why anyone would anyone would ever want to graph a function this way.  As far as I know, you have to use the option "discont=true" to remove the vertical segment, which is a hassle.  I consider this to be practically a bug.  I couldn't...

a) How can i use laplacetransform to solve with maple?

i₁ = i₂ + i₃ 
2i₁ + i₂ + 2i₁ = 30 + 20cos5 + 114sin5  
1/50 i₃ + 4i₃ - 2 i₂ = 0  

i₁(0) = 0

i₂(0)=0

i₃(0)=0

Plot

what should i do ? i face this message when i want to solve my equations? can anyone help me ?view the worksheet

Hello. I have three diff. equations that I believe I have solved correct. But how do I put this in maple? They must also plotted. Grateful for your help.

1)

y´´ + 2y´ + 2y = 5

Answer: y(x) = C₁ e^-x sinx + C₂ e^-x cosx + 5/2 

Plot.

2)

y´´ + 2y´ + 2y = sin5x

answer: y(x) = sin5/2 + C₁ e^-x

If I change a sample calendar the base calendar is also changed.

Dear Maple's expertise 

Here is the code in simple way with the output. 

The peoblem that I am calling the procedure with the same input but from time to time it gives different output shown in bold below. Although I make  restart for Mape?Is it bug in maple??Any Suggestions please.Should make clearing for some varibale and how?

Thanks in advance

The code is

Hi,

I have always been experiencing problems using a university server. It runs Red Hat 6.4 (Santiago) and Maple 17 X64.

The problem never occurs on Windows 7 SP1 X64 with Maple 17 X64.

Only reason I want to use the university machines is that it's "faster".

I had raised...

Hello,

Plotting the follwing function between x=0..2*Pi

I'm trying to plot a function that is defined as an integral of another function. I know that the function is quite smooth with no singularities over the region that i'm plotting. However, the resultant surface plot is bumpy/has holes in it. I tried changing the integration method and lowering epsilon to increase the precision but it still is not working. Can anyone help? Thanks for your time.
