Hello everyone!

I came here before once because of a problem I had with Maple and I really loved how well treated I was so I come here asking for help with another problem. An error is showing up on two of my programs on Maple (which I've included on the message). I don't even know what "invalid left hand assignment" means in my case so I have no idea how to solve the problem. I've searched about my problem, but nothing helped me much.

I'm trying to implement...

Hi

I want to simulate taking a card from to decks at the same time, and by doing it sufficiently many times, show that the probability is 1-(1/e).

I've implemented this in Python, but i'm new to maple. Here is what I've done so far.

randomDeck:=proc(n::integer)

  local deck:= [seq(1..52)];
local randomDeck:=[];

Hi,

I need to model the MapleSim ground as a hard ground. For example when the robot swing leg hits the ground, it should not have negative vertical position. Basically, the robot will move on a surface.

Thanks...

I would like to find a general solution for a problem. Now, I have written a fonction main(a1,a2,N1,N2) where a1 and a2 are two parametre symbolic, and N1 and N2 are two integers.

the function main(a1,a2,N1,N2)   can calculate every result with a paire of N1,N2 precisely given. but, I need the result for whatever N1 and N2. which means, I need a result in fonction of a1,a2,N1,N2 but not a single answer with N1 and N2 given.

How can I do this? thanks a lot.

Hi.

1) I am new to Maple TA and would like to ask a question about question respository. I go to: Class_Homepage >> Content_Manager >> Question_Repository >> Questions >> New Question. I then creare a (multiple-choice) question. In the end I click "submit". Where are these questions stored and how can they be accessed?

When I go to the repository, I do not see any questions there.

I want to find the parameters m to the  equation x^4 -(3*m+2)*x^2 + 3*m+3 = 0 has four distinct solutions and all of them were less than 2. I tried

eq:= x^4 -(3*m+2)*x^2 + 3*m+3:

sol:=[solve(eq=0,x)]:

d:=discrim(eq,x):

solve([d>0,sol[1]<2,sol[2]<2,sol[3]<2,sol[4]<2],m):

allvalues(%);

How to reduce my code?

Hi,

I need to expand a function of the form {[1]}.{[2]}.({[2, 3]}-{[3, 2]}).({[1, 3]}-{[3, 1]}), where '.' is for non-commutative multiplication. I need to get  {[1]}.{[2]}.{[2,3]}.{[1,3]} - {[1]}.{[2]}.{[2,3]}.{[3,1]} - ... (the order of matters).

Maple has a command 'expand', but that only works for normal products. eg. {[1]}*{[2]}*({[2, 3]}-{[3, 2]})*({[1, 3]}-{[3, 1]}).

Any help appreciated!

I am dealing with second order linear differeantial equations for RLC and forced RLC circiuts.

I am having trouble with plotting a solution curve in the phase plane.

> restart;

with(plots); with(DEtools);

L := 10; R := 20; C := 1/100;

de1 := diff(x(t), t) = y(t);

de2 := L*(diff(y(t), t))+R*y(t)+x(t)/C = 0;

DEplot({de1, de2}, [x(t), y(t)], t = 0 .. 5, [[x(0) = 10, y(0) = 0]], stepsize = 0.5,

Maple people:

The title is the question.  I defined a function in Maple, which works.  I am trying to get Maple to compute its derivatives.  I want to save the derivatives as functions.  Here is a code snippet.  The function itself works.  I have uploaded the worksheet.  Mapleprimes seems to have copied the entire worksheet into this question when I uploaded the worksheet.

Does anyone know if Maple has a counterpart to the Wolfram Lightweight Grid Manager that can be used with Maple 14 or Maple 16?

Hi

In earligere versions of maple (14 and 15) I yoused this code (program) to plot the area between functions, but it does not work in maple 17 (or 16).

integralplot2:=proc(f1,f2,a,b,{[color, colour] := blue,transparency := 0.5,numpoints:=500})     

local mingr,maxgr,variable,p,c,n,pts1,pts2,polys,i,xkoor,ytop,ybottom,yvals,plotf1,plotf2;          

if evalf(a)<evalf(b) then       

Hi

i want to find the eigenvalues of this system of two equations with two unknowns:

2.097*k = .9525000000*k^.35-2.2225*b/k^.65+.2 and

(2.097-2.0955/k^.67)*b = -.2

How i can do this in Maple?

Any help will be appreciated

I would like to determine the sign of a derivative of a function where I would make some restrictions on parameters and variables (e.g. larger zero). If a sign is not unambiguously possible, I would like Maple to give me an expression (threshold) for when the derivative is positive or not.

I would be very thankful for any hints!

(Notice: I am a Maple beginner!)

Best,

Max
