MaplePrimes Questions

Is there a maple function that implements the semantics of the μ-recursive function (Wikipedia)?

Hi,

 

I want to create a java file which includes maths

functions from maple, I try to do this with the maplet...

 

However, in order to start the programme, I must select

and open the maple...

 

So, can anyone tell me how to create an indepedent programme

which opens and works directly....?

 

 

A tool tip came up which says I can see the operations performed step-by-step. Can someone tell me where that feature is (what it's called)?

I have:

>solve(x+y+sqrt(x^2+y^2)

(24*(x-12))/(x-24)

 

I want to see step-by-step how Maple got to that answer. Thanks.

Hello All;

 

After having access to maple since maple 7 and never realy learning it, I decided that I would give it a good stab.

So far it's been cooperative. but I started from basic things wand worked my way through. I am now at the point where I need thisgs done and can't figure how to do them... shrort of rewriting the equations in the form I want.

I am working on exact differential equations and I need to convert this form:

Hey!

I'm really new on using maple 14 and I need help please.

I want to either connect maple 14 software with an oscilloscope for data acquisition or import the data captured by the oscilloscope to maple 14 and manipulate this data with the software for dynamic system analysis so I was wondering if anyone knows a programming code or a command to do this please =( I'm stuck

 

Thanks for your attention...

Hi!

I i have a 2nd order ODE where i want to chance the derivatives of x(t) and y(t) exactly at sqrt(x(t)^2+y(t)^2)=1 ,or before, as close to 1 as possible.

I found "event=" in/dsolve/numeric/events, where i can define the trigger and the action.

What is the difference between: "event=[[sqrt(...)-1,diff(x(t),t)=...],[sqrt(...)-1,diff(y(t),t)=...]]" and "event=[[sqrt(...)-1,[diff(x(t),t)=...,diff(y(t),t)=...]]]", because i get different results, which one is the correct form?

We have a list of cartesian coordinates [[x1,y1], [x2,y2],..., [xn,yn]], which describes some curve (say the way of a walking dog). We don't know any analytic expression for that curve. How to estimate the radius of curvature of the curve from below and above with Maple?

Hi,

I would like to define the following exceptions:

0/0 should be equal with 0, but any other x/0 should be infinity, if x>0 or -infinity, if x<0.

In the following example, I show what I achieved, however, I also would like to have equation (8) to be infinity.

BR,

Hi, I would like to numerically work out the profile of one expression (integral and BesselK function involved). But the computer was just jammed and came out nothing after long time waiting. I attach the worksheet below and maybe you could have a look at it or directly run it in your machine to check what is wrong, either my computer or the code itself. Thank you very much.

I am trying to plot a vector field with fieldplot, but the vector field components contain a numerical integration (i.e. evalf(Int(...,...)). However, maple refuses to plot it, and gives me this error mesasge

"Error, (in plots/fieldplot) no non-zero vectors found"

maple has no problem evaluation the vector field at any value of x, and y, and takes only a fraction of a second for each point. However, if i change the integral inside the vector field components to int(...

The following example tries to do the same thing two different ways.

Calling a procedure "M1" directly by name works fine.

Calling the same procedure by substitution fails to substitute, and when the substrituion is forced using "apply" I get an error message.

Why does the substitution not work, and where is the error?

Because of the complexity of my problem, I need to use substitute (or anything else equivalent) instead of directly calling the procedure by name.

I am new to maple, and looking for som tourturial to get me started. My school dont offer any education in the program.

 

Can maple do the same things as matlab? i have a little program i wrote i matlab. Is it possible for me to write that i maple?

thanks, this worked for me. As for the

eqn1 := u = V * cos(a) * cos(b);

eqn2 := v = V*sin(b);

eqn3 := w = V*sin(a)*cos(b);

res:=solve({eqn1, eqn2, eqn3}, {V,a,b});

map(sin, res[3]);

simplify(%);

gives sin(b) = v / ( RootOf( _Z^2 - v^2 - w^2 - u^2);

map(x->x^2, %);

simplify(%);

gives

sin(b)^2 = v^2 / (v^2 + w^2 + u^2), which has no _Z , but is not right. is there a better way to eliminate _Z ?

The equations are x+2y+3z=4, x +ky+4z=6, x+2y+ (k+2)z=6. I entered the eqautions and got up to this point. > eqlist := [eqn1, eqn2, eqn3]; and got the equations repeated back to be
> varlist := [x, y, z]; and got the 3 variables repeated back to me. When I tried to genrate the matrix, I put in. A := genmatrix(eqlist, varlist, flag), and got genmatrix([x+2*y+3*z = 4, x+ky+4*z = 6, x+2*y+z(k+2) = 6], [x, y, z], flag). What did I enter wrong? did I have to incorporate...
