i'm here once again and thanks for all your useful replies. They've all being really helpful. my problem this time around is how to create a table of values. I already have the values at hand but would like to tabulate them so that i can have a better view of everything at ponce. and also to make comparism at some point t or width h. Is there a maple function that can do this conveniently?

How do I plot the imaginary or real part of a complex valued function

e.g.

E:=y^2+x^2=1

I tried:

E1:=eval(E,{y=y1+I*y2,x=x1+I*x2})

implicitplot3d(E1,x1=-3..3,x2=-3..3,y1=-3..3)

but which does not work

The Single Variable Calculus Approximate Integration Tutor (and the function ApproximateInt) work fine for the built-in example of sin(x) from 0 to Pi.  But if you change it to sin(Pi*x) from 0 to 1 then plot options are ignored.  And if you ask to integrate sin(3.1415926*x) from 0 to 1, then it works again.  Is there a work-around?

I'm pretty new to Maple and have the following question about Maple plots. Why does Maple plot a vertical line for the undfined x values?

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.

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.
