Hi,

I asked a similar question some time ago : http://www.mapleprimes.com/questions/123925-Shortcut-Key-AltShiftF6.

I'm still on Maple 13, and I still have not found a way to switch between tabs/windows using the keyboard.I am in the one Maple session (ie I haven't started a new one).

I tried all suggested combinations, including all combinations of Ctrl, Alt and Shift...

Hello,

I have a question. I need to rewrite the following function

Vo:= (1/((1/R2+1/(1.5*10^6))*(1/(1/R2+1/(1.5*10^6))+2.45*10^3-R2)));

To this form

R2:= ....Vo....

How can i do this in maple? 

Hi,

I would like to discribe the following function.

w(ξ,s):=N(s)*w(ξ)

N(s) and w(ξ) are both matrix. I have defined N(s) but will be searching for w(ξ) much later in the process. Why does it not allow me to define a partial derivative of w(ξ) now for future use? d/dξ(w(ξ)) is not allowed. it says that "Error, invalid input: w uses a 2nd argument, s, which is missing". But my w(ξ) only depends on the variable ξ.

2nd question, how do i tell maple that x...

A simple question. I have this:

k*(2x+y-3z+2)+s*(5x+5y-4z+3)=0

And I want to group it by x, y, z, so that I would get:

x*(2k+5s)+y(k+5s)...=0

I'm using Maple 11.

Hello Everybody.

Im new to Maple, so i have a couple of questions. In the last few days I have learned the basic of Maple, and now i would like to solve an differential equation.

The Math question is:

Enter the solution of differential equation:

In the link i have put in the informations from the math question.

Hey there, this is my first post here, so hello to everyone.

I have (so far) one question. I have a circle equation like

x²+y²-6y+6=0

I know, that on a paper, I can convert it to the "normal" circle equation, from which I can read the middle point and radius of the circle. And now my question is, how to convert in in maple? I am using the 11th version.

I have tried solving this equation and (x-a)

Hi there

I have, for a while, been trying to find a way to force maple to display the unit im inputting. 

Im studying to be an engineer, and for an example the unit i often would like displayed is kilonewtons per square metre (kN/m2). 

Once i hit enter, maple converts it to Pa, which isnt really usable for me ... 

The question is, is there any way to stop maple from doing the conversion in output......

first, thank you for reminding me, acer.

2nd, I received a mail that someone posted a new comment, but now I can't find my post, where is it?

3rd, can someone tell me how to ask an old question if no one answers for that question?

thank you in advance.

my old question is here:

hello , i m a student and i have a little question

in fact , i wrote this program bur it doesn't work until now , i dont knew why , please if you have an idea tell it to me as soon as possible ,

thanks

I need to create an ellipse and an ellipsoid (ellipse in 3D) through code. How would I be able to do this? Can someone please give me an example for each?

Also, I will need to create a line for an ellipse and a plane for an ellipsoid that intersect. Would I be able to find the intersecting points? Would I be able to find the function for the curve line that is created when a plane intersects an ellipsoid? Also, how would I find the surface area and volume...

Dear all, 

I have two questions regarding truncated normal distribution.

1. Is there a convenient way in Maple to compute and plot the density function of a truncated normal distribution? I know that in Maple, after creating a random variable, I can use the function Statistics:-PDF to compute the density function, and use DensityPlot to draw the function. But for truncated distribution, I have to compute it manually by doing integration to compute the normalized...

i have a sample but i dont understand what does makes, please help me ...

best regards

MaxVar(1,1)=evalf((1+RanNum(1,1)()/100))

my question is about the parentheses after the matrix RanNum(1,1), why is here ¿? what does makes ¿?

Hi there,

I just wonder if we can plot phase plane with arrows for more than 2 equations in Maple. For example:

DE:={D(x)(t)=y(t)-z(t),D(y)(t)=z(t)-x(t),D(z)(t)=x(t)-y(t)}

DEplot(DE,{x(t),y(t),z(t)},t=-2..2,[[x(0)=1,y(0)=0,z(0)=2]],linecolour=black,stepsize=0.1,scene=[x(t),y(t)],arrows=small)

This one doesn't give me a plot with arrows.

Thanks in advance for your assistance.

Regards,

Masoum
