Who deleted my post - "How to factor out specific parts from expression"

Hi,

I want to solve system of  PDE equations by maple and i dont know how can i write it codes that can solve them for me. Can anyone help me please??!!

So I just noticed that if you want to animate something in real time, the best you can achieve is something close but not exact.

For example lets say we have a ball travelling 22 m/s over 1000 m and I want to animate that in real time. 

ball := proc(x, y) plots[pointplot]([[x, y]], color = blue, symbol = solidcircle, symbolsize = 40); end proc:
animate(ball, [22*t, 0], t = 0 .. 1000/22, frames = floor(1000/22));

frames has to be an integer value so determining how long it will take and adjusting the frames to 1 frame per second.  It requires a bit of manipulation to get it right.  Is there a better way?  I suppose boosting the frame rate and increasing the number of frames would work but then it becomes cumbersome and any large period of times would use a high number of frames and consume enormous amounts of memory. 

Every time I open Maple it has the invitation to Login in the top right-hand corner.  I would like to sign in but have had quite a bit of trouble doing that.  I have a user name and password with Maplesoft web store and the same for MaplePrimes.  Should either of these work to log in?

Hi, i need some help for a homework.

Here is the statement

You must first animate a series of linear transformations on the polygon formed by the following couples: [5, 0], [6., 0], [6, 3], [10, 3], [7, 5], [9, 5], [7, 7], [8, 7], [5.5, 9], [3, 7], [4, 7], [2, 5], [4, 5], [1, 3], [5, 3] It will be necessary to make, at the same time, a rotation around a line making an angle k with the axis of x, a rotation of an angle k and a scaling of variable ratio (but equal to 3 at the end animation). The k animation parameter should range from 0 to 180. I suggest you use the color green for your polygon. Then you will need to create a second animation by entering these command lines: SnowPoints: = seq ([- 30 + i, 30 - j / 2 * sin (i + j)], i = 0 .. 60): snow: = animate (pointplot, [[PointsNeige], color = black], j = 0 .. 60, view = [-30 .. 30, 0 .. 30]) : Finally, you will have to roll both animations at the same time.

Thanks for the help !

In the obselote book programming examples it is using array's as data type

Is het easier to use A Vector or Matrix as datatype?

Dear all

I compute the solution of first order nonlinear ode, supplied to initial condition.

The code is written, the exact solution is derived.

 plot the solution in a small interval like (0,1/5) I see that there is no difference between exact and semi-analytical soluton.

But, If I plot the solution in other interval like (0,1) or (0,2), It is noticed that the semi-analytical solution is different to the exact solution. 
Thansk you in advance for your help

Apparently a colon within a string causes some issues when generating a XMLElement.

Didn't find anything in Maple Help about that though.

Good day everyone,

I have problem-solving this system of equations using Iterative Projection Theorem. Anyone with a better explanations please.

The equation is as stated below. 

Solve this set of equations using the iterative projection theorem.

(x₁ - 2)² + (2x₂² - 6)² - 5 = 0

(x₁² - 4)² + (x₂ - 10)² - 39 = 0

Take the provisional values of  x₁ and x₂ as x⁰₁ = 5, x⁰₂ = 4, 

Thank you in anticipation

Good day everyone, please I'm soliciting help on how to solve PDE in Maple. I know how to solve ODE but I don't know how to go about PDE. The problem I want to solve is attached as an attachment. If epsilon is zero, then the problem reduces to ODE which can easily be solved, but epsilon is not supposed to be zero. please I need your help, thank you in anticipation.

Hi Maple Users,

Microsoft is enticing me to upgrade to Windows 11 from 10 for free. I am a bit hesitant because I don't know if Maple 2021 will continue working as well as in Windows 10. Does anyone have any thoughts or wisdom to share.

Thank you.

How do i get to the 2nd line for a multiple problem?
