How to interpolate in terms of any form of algebra in maple?

For example, to interpolate a time series in terms of exponential or mixed with cos and sin?

I guess I have an easy question here. How do you write stuff in Maple which you don't want displayed? For example, if I wanted to set alpha=1 but I didn't want that printed after pressing enter?

Cheers

Hi all forum people, I need use the maple for symbolic solutions, I am a beginner user.

I read about the isolate, solve, equations, expressions and functions in maple, I have a great confusion in my head.

My needs are, make a equations (with currents and voltages) and isolate any variable in a time, and combine them with another equations.

  ic=vin/L*Ton+im

if=(vin-vo)/L*Toff+im

dil/dt=(if-im)/T

Hello friends,

I am using MAPLE 14. I have the following problems. I would like to plot the sequence of points "ww", and the constant funcion  (ordenate) 1/3.  The plot of my commands is ok in terms of the "spirit" of the output, but I would like

1. That in the abscisa appears values larger than 10..say  50.

2. The (horizontal)  line of the constant funcion 1/3 = function of (n)  is thinner (in the current output, this line is too thick).

While doing some Maple plotting I found myself asking why a high-end scientific computation application like Maple, which is capable of essentially very high ("arbitrary") precision floating-point computation, sometimes makes only crude use of hardware precision plot drivers. I looked around a bit, and found that and related issues are not restricted to Maple.

Let's look first at Maxima. Here's my first example, in Maxima (not Maple) syntax,

Maple cannot find maximum/extrema for this piecewise function?

Find all the solutions of the equation y*diff(u(x,y),x)-sin(x)*diff(u(x,y),y)=u(x,y)^2 in a neighborgood of the origin (0,0).

I have this question to answer but I have no clue whatsoever what to do. I'm a first year student so this Maple stuff is all pretty much new to me. Can't seem to figure out what "det" is. 

For the matrices A = Matrix([[2,-1,1],[3,1,-1],[0,2,2]]) and B =  Matrix([[2,1,5],[4,3,8],[0,-1,0]]) verify that det(A . B) = det(A) det(B)

How do I do this?

Dear All,

could anyone of you provide me with some guidance on how to tackle my issue,i.e. unable to launch Maple 14 on Mac OS 10.5.8,please? Its icon bounces off and that's that.

Hi all,

I have a large system of equations in matrix form A x = b (A and b are constituated with numbers)

The rank of the matrice A is 1524 by 1524

How to solve numerically the system with maple. I searched in maple help and mapleprimes questions but I have not got answer.

If maple has a limitation in solving large system of equation numerically,

Is it possible to export the matrices A and b in matlab and solve the system in matlab and...

Hello! Anybody can help my to have this problem?

A^2+3*A+Delta*I = 0;

I want calculate 'a' and 'b' whit 'x' and 'y', and it's my code:

++++++++++++++++

But this is wrong, but I dont know...

Thank you!!!!

(sorry for my English)

     I suppose that Maple 15 is now in the stage of beta testing, but I have not served as a beta tester for a few years.

     Those scientists and mathematicians who apply Maple in teaching mathematics, science and engineering or who use it in their research naturally wonder what will be in store in the next release to complement and to extend the features in preceding releases. 

     I have no...

int(sqrt(1 + sec(x)^2), x)

int(sqrt(2 + tan(x)^2), x)

With Maple 13, which is the latest version on the computer on which I tested these integrals (that originated with a

senior scientist in Australia), the former yields a reasonably compact answer, but the latter yields an extensive

output containing Elliptic functions of various kinds.  The two integrands are trigonometric identities.  What is the

problem here?

how can i input and solve  the one dimensional wave equation with intial and boundry conditions???
