Suppose that you have simple algebra, and you want to numerically solve the equation ok you press "numerically solve"; but, my question is how you do it if you want to see

how maple get the result step, by step?

Following the midi crash course written by Daniel White, and using a table of midi note numbers, it is rather easy to write a Maple procedure producing midi files. Here is an example that I posted in Simple Sounds thread, slightly modified by adding an instrument as a 3rd parameter:

I have a sequence of numbers including only 0,1,2,3,4,5,6,7's and I want to create a file that will play music according to the sequence of numbers.  For a 0 play middle C. For 1 play D, For 2 play E, etc.

Is there a simple way to do this.  I know very little about sound, .WAV files, etc.

First of all, sorry for my bad english!

I am so lucky to live in denmark, and in denmark we use degrees instead of radians in math. So therefor my problem is, how do i make maple 12 use degrees?

Thanks!

Dear Sir,

I want to know how we can convert a Maple worksheet directly in eps so that we get a figure of the sheet in Latex. Otherwise please suggest  other ways to include the worksheet in Latex.

Hey there,

Here the problem that I'm facing:

I have an equation that as follow:

B0+B1*x+B2*x^2+B3*x^3+B4*x^4+B5*x^5+B6*x^6+B7*x^7= (a0+a1*x+a2*x^2+a3*x^3+a4*x^4)^powerN / (c0+c1*x+c2*x^2+c3*x^3)

with all the B's are known coefficients; what I'm trying to do here is to determine the coefficients for a's and c's, as well as the powerN (may and may not be an integer). Is there any way that I can solve that?

Thanks!!!

How can i use dot notation in time derivation equations?

I want to write a variable with a dot on top, but I can't.

any idea?

thanks

...to extract the installer to. <sic>.

I get this error when attempting to upgrade from MAPLE 10 to 12. I went to the Maple site, made the credit card purchase/entered my serial number, downloaded installer, and voila - zip.

Running XP Home 2002, SP3. 8800 GT, 3.4 GHz Pentium, 2G RAM.

No location I select seems to work. I did check out the FAQ before posting, and have an email in to Support.

The font I get in Maple 12 when I use it on Windows XP is, for lack of a better word, thin. Can I make the font a bit more readeable? Thanks in advance.

I want to solve the following set of ODEs numerically using shooting techniques

they are:

de := diff(x(t), t)+2*(diff(x(t), t))^2-y(t)-.1*z(t) = 0, diff(y(t), `$`(t, 2))-x(t)*(diff(y(t), t)) = 0, .2*(diff(z(t), `$`(t, 2)))-x(t)*(diff(z(t), t)) = 0; bc := y(0) = 1, z(0) = 1, x(0) = 0, x(infinity) = 0, y(infinity) = 0, z(infinity) = 0; gn := desolveSH({bc, de}, t = 0 .. 20, info = 1, numeric)

Any help
