I am currently taking a course in quantum mechanics using the second edition of McQuarrie's Quantum Chemistry text. I plan to take a QM II course, more concentrating on atomic and molecular spectra. I have been using Mathcad 15, which includes Maple functionality (please pardon my stating the obvious). Mathcad, however, seems to lack functionality (or I have not found it) that would be helpful, like the ability to easily define an operator. Since...

Find the polynomial y=f(x) such that f(-6)=2400,f(-4)=432,f(-3)=120,f(-2)=16,f(-1)=0,f(0)=0,f(1)=-8,f(2)=0

Hello, I export a plot in an eps format (since other formats have lower resolutions) and want to insert it into Word 2007.

But, everytime when I do this, the Word 2007 will respond error occurred while importing the file.

Could anyone help me to resolve this problem? 

Thank you very much.

Hi All,

Thanks for checking out this question. I am working a semi-strange integral and am having trouble getting Maple to evaluate it:

I am getting the response:

"Warning, unable to determine if 464/19 is between 6 and x; try to use assumptions or use the AllSolutions option"

I'm...

I have some numerical data, which are very accurate (500 digits) and want to copy them on a text file.

For pratical reason I would like the procedure writefile to write just 20 digits figures: which is the right syntax to use?

Dear Mapleprimes,

I need to plot a graph for different values of a specific parameter, sigma. It would be great if I could plot them in two separate coordinate systems right next to each other, such that I can copy paste them into my article. Could anyone help me with that?

Cheers,

Dear Mapleprimes,

I have a problem with a graph. I need to plot the following:

plot({1/(1-x)}, x=0..2, y=0..4);

But I don't want the vertical line at x=1. How do I get rid of it?

Cheers,

Christian

How it works to be so fast?

Is it somehow related to other wonderful tetralogy:

Hi everyone,

One minor question:

what would be the code to extract data in the form of 2-d points from the output of dsolve/numeric... output=Array/array?

say, I have 6-d ODE system and I wnat to extract data in the form of 2-d arrays of number s and then approximate this with some polynomials via Curve Fitting package.

For this I need the data to be represented as -dim matrices  for every variable.

Thanks for any help.

We are trying to obtain an analytical solution of an integral in Maple. When solved numerically the integral converges, but we are not able to get an analytical solution. Any ideas?

The constants in the integral is computed independently, not sure if knowing them can help. The values are r=0.06, kappa=2.6, myksi=2.18, rho=-0.21, stdk=382.2, stds=47.8, kji=52.9 and ksi=62.3. We kind of need the analytical solution to handle the expression in further calculations, and...

how can i overcome the error that i am being given for the problem below 3*t*d(t,x(t),diff(x(t),t))² = 0

Quick one,

How do I count the number of terms in a polynomial

i.e. x^3+x+1 has 3 terms. I have big polynomials with hundreds of time and I want a way to count them

Many thanks

HI all,

I am trying to figure out in MAPLE how can I write     A * sin*theta + B* cos* theta  in the form as follows:
