I am attempting to combine the sum of two sinusoids having the same frequency in Maple (e.g. A*cos(10*x) + B*sin(10*x + Pi/3) = M*cos(10*x + phi) )

The long way through this is to break each term up into cartesian components and add them (x = A + B*cos(Pi/3 + 3*Pi/2) , y = B*sin(Pi/3 + 3*Pi/2) ). Following the summation, they can be converted back to polar (M = sqrt( x^2 + y^2 ) and phi = arctan(y/x)).

This is a long process for me and if my graphing calculator...

Each of my two previous two blog posts (Maple Gems, More Maple Gems) contained five "gems" from my Little Red Book of Maple Magic, a red ring-binder in which I record...

Hi there,

I am currently working on an ODE model with a diffusion term and I have to analyse it analytically (if possible) with Maple12.

With the dsolve function I have a solution but based on BesselJ and BesselY functions.

My questions are:

• Do you know if it's possible to have a solution without these functions?
• When I add the IBCs conditions, the system is inconsistent, do you understand why?

Hi I'm having trouble generating the mandlebrot set using maple... i only have a very basic knowledge of this programme.
>plot3d([-2, 0.7], [0.7, 3] orientation = [-90,0], grid = [250,250], style = patchnogrid, scaling = constrained, colour = mandelbrot);

The above code is giving me trouble, it keeps coming up with an error missing operator or ';'
I don't see anything wrong with it though....

Hi there,

I am trying to find the numerical value of the following integral:

evalf(int((T-a*n*(-T)^n+2*a*n^2*(-T)^n)/(T^2-a*T*(-T)^n+2*a*n^2*(-T)^n-2*a*n*(-T)^n), T = -90000 .. -29400)).

However, Maple just returns the integral. What am I doing wrong? 

Thanks!

Hello

Is there a way to change FPS via options in an animated curve?

Hello,

I have several figures generated by ZeroPolePlot command, I feel the figures are not the size which I expect, so I can make the figures a little bigger or smaller by dragging the edge of them. But for several figures, it is difficult to make them to be just the same size, namely, all the figures' height=200, weidth=200. In one thread, Mr. Robert...

The orginial equation to solve is : x" + F(x) = sin 4t

initial conditions : x(0) = 0, x'(0) =1;

F(x) = { bx, x>= 0 and ax, x<0}

I need to do three different values for b = 1, a = 4, then b = 64, a = 4, finially  b = 36, a = 25,

Thanks for any insite I am new to the program.

I have a simple request that I hope someone can provide, I do not think it would be too much trouble.

I use Maple 12, hence no Maple cloud, but while viewing one of the maple 14 demonstration videos there was a Maplesoft document in the cloud called -  Example: Mortgage calculator by maplesoft, I would like to have a look at it.  Upon using google and the maplesoft application center, I was unable to find such a document. I am guessing it only exists in the maple cloud.

SORRY IGNORE THE LAST GRAPH AND PLOT IT NOTHING TO DO WITH THIS QUESTION!!

I'm having a few problems with differentiating in Maple. I have a potential function U given by:

U[c] := (1/2)*r^2+M[1]/r[1]+M[2]/r[2];

U[r] := r^2*(M[1]*M[2]-3)/(2*c^2)+((x(tau)+diff(y(tau), tau))^2+(y(tau)-(diff(x(tau), tau)))^2)^2/(8*c^2)+3*(M[1]/r[1]+M[2]/r[2])*((x(tau)+diff(y(tau), tau))^2+(y(tau)-(diff(x(tau), tau)))^2)/(2*c^2)-(M[1]/r[1]+M[2]/r[2])^2/(2*c^2)-M[1]*M[2]*(1/r[1]+(1/r[1]-1/r[2])*(1-3*mu-7*x(tau)-8*(diff(y(tau), tau)))+y(tau)^2*(M[2]/r[1]^3+M[1]/r[2]^3))/(2*c^2);

Hi All,

Is using the NAG package the right way to go about creating the delaunay triangulation of a set of points in 3 dimensions. My points all lie on a surface in R^3.

Thanks. 

Hi All,

Recently I upgraded to Maple 14 from Maple 13, and I've encountered a strange behavior in Maple 14 that doesn't appear in Maple 13. By the definition of Spherical harmonic functions in Maple,  

SphericalY(2*l, -2*l, theta, phi) = SphericalY(2*l, 2*l, theta, phi).

And this is true in Maple 13, however not Maple 14. Can you reproduce this behavior in Maple 14? Or have I done something else that might be causing this?

Thank you for any help you can provide.

Hi there,

I have defined an own type MyType wich is internally just a list ['MyType', A, B] with let's say two lists A,B and the symbol 'MyType' as first element (to identify the type).

Now, if I define

X := MyType('MyType', A, B);

is there a possibility to extract A out of X by something like

X[2]

or even better X[1] (thus skipping the first one)? The only thing I know is op(2, X).

Hello,

I need to create a new bernoulli distribution such that P(I=1) = q = 1-P(I=-1).

I did U:=Distribution(PDF=(t->piecewise(t=-1,1-q,t=1,q,0))); but Maple gives me back:

module() option Distribution, Continuous; export...   instead of:

module() option Distribution, Discrete; export...  since the distribution is discrete!!

Do you know a way to force U to be a discrete distribution, cause otherwise I get all moments=0.
