Problem. Find the coordinates of the point M on the sphere (S): x^2 + y^2 + z^2-2*x+4*y+2*z-3=0 such that the distance from the point M 

This should be a blog post but there is no option for ordinary mapleprimers. 

If you have a gmail account you can access the data on google insights (what people search for on google and where in the world is that keyword searched the most).  Actually you don't need gmail but you don't get access to the full data and your limited to a few searches.  Using Maples internet connectivity commands I'm sure could prove to create some interesting apps.

I want to write a code to generate Legendre Polynomials using the Gram-Schmidt Process. I have no experience with programing. Here is how the process should work:

Given "(f) = {f[0]=1, f[1]=x , f[2]=x^(2) , f[3]=x^(3) , ... , f[n]=x^(n)} "
       
Find the Legendre Polynomials: "{P[0] , P[1] , P[2] , P[3] , ... , P[n]}"

First,  P[0]=f[0]=1

then, the rest are defined recursively by

P[1]=f[1]-(()/())*P[0] = x

Hi All,

I want to create a MapleSim Custom Component which has a vector input and the output is a matrix. In this case how can I define the system (Dynamic system sys:=DynamicSystems[?])? Hence, how can I assign these input/output to component ports?

Thanks

I have a problem with animations using a density plot as background.

The density plot covers the animation.

Here is an example:

plt:=densityplot(-(x^2+y^2),x=-1..1,y=-1..1);
animate(plot,[[sin(r)*cos(t),sin(r)*sin(t),t=0..2*Pi],thickness=10],r=0..Pi,background=plt);

Can this be solved? 

Best regards

Hi,

I am trying to create a do loop to generate y values from a series of vectors containing the x's. In the end, I will be exporting this data to Excel, so I want to put it into a Vector.

My problem is that sometimes I have 11 x's and sometimes I only have 9 x's.

observed := rtable(1 .. 2, 1 .. 3)

for k from 1 to 2 do 

for j from 1 to 3 do 

observed[k][j] := evalf(subs(HK[1] = C1[k, 1...

Hi guys,

I am fairly new to Maple so please go easy on me!

I have seen the Mathieu equation in my chemistry book regarding quadrupole mass spectrometer. I want to know how I can use Maple to solve the equation and to plot a 'stability diagram'?

The equation is seen here (in this link):

I have Maple 12. I am trying find integer partition of 20 into size 5 each. This can be accomplished in mathematica, using the command of 

IntegerPartitions[20,{5}]

Maple does have Partition command but there is no way to use that command to produce an output of size n partition.

For example Partition(20,5) results in partitions of 20 with 5 being the largest integer. That is not what I want. I need to...

How do i solve a simple trigonometric equation? For example sin(2*x) = -sqrt(3)/2.

I am unable to find where the problem is within a plot. Here is the error message: Error, (in plot) incorrect first argument [(k-1)*r*(cos(t)+cos(k-1)*t/(k-1)), (k-1)*r*(sin*t-sin(k-1)*t/(k-1)), t = 1 .. 1, r = 1 .. 1, k = 3 .. 3]

Is there a symbol or something that i am supposed to be looking for in the error message so i know where the error is occuring?

How to draw slope field associated to differential equation: dy/dt = sin(ty) on Maple software?

I know I can use try catch but why doesn't this work?

is(tan((1/2)*Pi) = "Error, (in tan) numeric exception: division by zero")
Error, (in tan) numeric exception: division by zero

It is a string value error that should be true in the test shouldn't it?   

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...

Hi,

A simple question. How do you echo 2+2 to the output without Maple calculating it and putting 4 in the output ?

thanks,
Andrew

Firstly applogies for if this question has been asked before.

I am trying to plot a simple epidemic model for where I can change the rates.

My equations are:

de1:= diff(X(t),t)=a*X(t).Y(t);

de2:=diff(Y(t),t)=a*X(t).Y(t) - b*Y(t);

where X is susceptibles and Y is infected.

I would like to be able to produce a graph with the susceptible and infected plotted. Where i can change the initial conditions of X(0) and Y(0) using sliders...
