@kongstad1998 I agree with Joe's remark.  There is nothing useful in this file.  You have to start over.

@Christopher2222 Comparison listed in document title is for Maple 18.01

Adobe acrobat can read an eps file.  From there, you can save it as a Word doc, or cut and paste the image out of Acrobat into Word.

@leoteo IBC = {U1(0, 0) = 0, U2(0, 0) = 0, U3(0, 0) = 0}; is missing the assignment operator.

IBC:={U1(0, 0) = 0, U2(0, 0) = 0, U3(0, 0) = 0};

pdsolve(PDEs, IBC, (U1, U2, U3), nummeric); numeric is spelled incorrectly.  You have an extra m.

There are 3 dependent variables, but you have 4 PDE's.  They have to be the same.

Welcome.  Let us know if you need help with Maple.  Post your questions as well as any Maple code that you have tried, but are having a hard time with.

@jonlg The assign command with the (%) sign takes the previous lines output, and assigns the solutions on the right hand side to the left hand side of C(t) and V(t).  In your case, without assign(%), C(t), and V(t) would be blank if you tried to use them later on.  The % is also known as the Ditto Operator.

In general, the percent sign is used to operate on the previous command line output.  ?% for more help on this.

@Vesnog   See worksheet below.

Download plot.mws

Download the worksheets individually, and then open them in Maple.  The zip archive does not include all of the worksheets, it includes an "m" file that can be read into Maple, with procedures for differential equations.  Most of the worksheets need this file in order for them to work properly.

You can create a data set for one axis and another data set for the other axis and plot them against each other (I think this is what you are asking for).

The first seq creates the x-axis for 1/x.

The second seq creates y-axis for x^2

>restart:
>plot([seq(1/x, x = 0.1 .. 1,.1)], ([seq(x^2, x = 0.1 .. 1,.1)]), style = line);

@Johe1 The output of the code that Axel has provided yields

plot(4*(1/4)^t*(1/3),t=0..20);

Will give you the graph.  Where is it that you had a problem?

See link here.  Windows 7 does not include sndrec32 any more (if you are using that OS).  A system call to any media player will (should) work.

Greetings.  Can you post an image of the Mathematica plot?  Does it look like the plot below?

Georgios

int(sqrt(1+diff(f(x), x)^2), x= 0..17.0);

will also give 30.75115135 as an answer.

Notice the end limit of the integral, being represented as a floating point number.

The end result is the same as evalf(Int());

Thanks Carl for pointing out my reversal of D and Lett.  I should have cut and pasted the example from the help page directly.

Have you tried downloading the code from the authors website.  When I did this for your example above, and ran it in Maple 17, it executed without errors.

See link here.
