Hi, Would appreciate some help regarding testing Euler's method in Maple. I have the following function: dy/dt = - 3*y, y(0)=2, delta t =0.2. Is there a programme in Maple that would allow to test this method by performing iterations / plotting a graph? Have already tried Maple help. Thanx in advance. antonio

I wanted to use (one of the variouos) cosine transforms DCT, but only find FFT in Maple12.

Googling did not give me more (except there seem to recipes to reduce my theme in some
brute (?) ways to a FFT problem).

Is there any Maple solution around (even if I can use Clenshaw's algorithm having only a
moderate size - but want to see some generalisation ...)?

A box contains 10bulbs of which 5 are defective. 3 are selected at random and  put in sockets.Find the expected value and variance for the number of defective bulbs in the selection.

Maybe I'm missing something (different definition), but the spherical harmonic function SphericalY gives wrong results. For example, SphericalY(0,0,0,0) evaluates to 0, but should be 1/(2*sqrt(Pi)) (see e.g. http://en.wikipedia.org/wiki/Spherical_harmonic, also Mathematica gives this answer). Note that there is no possibility for arguments mismatch in this case. Do you have any explanation? (I'm using Maple 10.)

I'm trying to use the scientific constants package to evaluate the product of certain constants. 

What I'm trying to calculate is the value

(mu*e^(4)/(2*hbar^2), where mu is the reduced mass of the electron and proton, and hbar is Plancks's Constant divided by 2*Pi.

This is for a Quantum Mechanics problem where I'm supposed to show for the large quantum number limit, i.e. large n, this angular frequency approaches values for the classical angular frequency of an ordinary rotating object.

I want the asymptotics for EllipticF(z,k) w.r.t. z (yes, not k).

My example is F:=I*EllipticF(c*I/x,k), c=2-2^(1/2),k=3+2*2^(1/2)
and I want the limit x ---> 0+.

  MultiSeries:-limit(E,x=0);

results in 0.54... + 0.54...*I (real = imag, positive value).

  MultiSeries:-series(E,x,3);

gives (after clearing the output) the same for setting x=0.


For Numerics my setting is Digits:=24 and eps:=1/10^18.

  subs(c=2-2^(1/2), k=3+2*2^(1/2), F...

Hello,

I have a question on the efficient usage of map command.

 

Suppose I have a function of two variables:

a:=(x,y)->sin(x)*cos(y)

 

I would like to evaluate the function using fixed values of x and y (i.e. grid search problem):

f:=x->x*Pi/180

X:=f(<seq(0..360,45)>)

Y:=f(<seq(0..360,60)>)

Suppose that the Hamiltonian is invariant under time reversal:

[H,T] = 0.

Show that, nevertheless, an eigenvalue of T is not a conserved quantity.

 

v/r,

Hi guys. I have a sets of N data points in the form [x_component(1), y_component(1)], [x_component(2), y_component(2)], ... [x_component(N), y_component(N)] that I want to plot as points and draw the regression line through them. I know how to plot the regression line with the data points in the form [x_component(1), x_component(2), ..., x_component(N)] and [y_component(1), y_component(2), ..., y_component(N)] So my question is how to isolate all the x components and all the y components from my data points?

Hi,

How can I create a help file in maple for a user function ?

Thanks

How do I get rid of the right-hand pallete dock ?

Hello,

 

this problem has been bugging me for months. I am defining functions with "if" in their definition.  These functions seem to be well defined, without any problem. Then I do sum and something goes wrong.  I have tried to isolate the problem to give you an example:

 

Hello, I am new to Maple, and I have a novice question on rounding with evalf function.

 

I have an expression:

m:=(x,y)->126*cos(a)^2*(cos(x)-sin(x)*cos(y+b+c)*tan(a))-42;

 

Then I set some parameters as constants:

g:=x->x*Pi/180;

a:=g(58); b:=g(-45); c:=g(100);

 

Hi Friends,

 

May I know How do I solve numerical differntial equation in MAPLE 12..?

My equation is very big..please send your valuable suggestion

 

Thanks

What is the value of u1 in this u substitution to go from -2*Pi*(int(sqrt(-3*u^2+4), u = 1 .. 0)) to -2*Pi*(int((4/3)*sqrt(3)*cos(u1)^2, u1 = (1/3)*Pi .. 0))? I'm just not seeing it.
