This is going to seem really stupid, but I've never used Maple before and I just can't figure out what I'm doing wrong. I'm trying to plot a graph of 3 functions (or rather, one function and its first and second derivatives), and it seems like I have the right formula typed but no graph is appearing. This is what I entered:

g0 := x^(2/3)sin(x);

g1 := diff(g0,x);

g2 := diff(g1,x);

p0 := plot(g0, x=0..3, y=0..3):

p1 := plot(g1, x=0..3, y=0..3):

p2 := plot(g2, x=0..3, y=0..3):

display({p0,p1,p2});

hi all, sorry, i'm a newbie on maple

i have to simplify some equation, then i heard that it can be done by maple. so i tried using maple 10 to simplify my equation.

but after i write down the equation, and press enter, i got "unable to match delimiters" message. what should i do to get the simplified equation?

here is the equation:

I trying to fit an Eckartfunction with 3 parameters to my curve I've calculated with gaussian03 (IRC).

my given points for the curve are:

Hello,

with(VectorCalculus):

SetCoordinates( 'cartesian'[x,y] ):

How do I make  animations of an ellipse? E.g. stretching, rotating, translating in both the x an y direction? I thought it was easy task, but after several hours I still have no solution.

Anyone?

kind regards,

Harry Garst

is there any way that cartesian eqns can be converted to parametric  and vice versa in maple?

den1 := (1/2)*((2+x^2)*sqrt(4+x^2)+2*sqrt(4+x^2)*cos(t*sqrt(4+x^2)*tau/`ℏ`)+sqrt(4+x^2)*(cos(t*x*tau/`ℏ`))(2+(2+x^2)*cos(t*sqrt(4+x^2)*tau/`ℏ`))+x*(4+x^2)*sin(t*x*tau/`ℏ`)*sin(t*sqrt(4+x^2)*tau/`ℏ`))/(4+x^2)^(3/2)

den2 := 4*cos((1/2)*t*x*tau/`ℏ`)^2*sin((1/2)*t*sqrt(4+x^2)*tau/`ℏ`)^2/(4+x^2);

den3 := 4*sin((1/2)*t*x*tau/`ℏ`)^2*sin((1/2)*t*sqrt(4+x^2)*tau/`ℏ`)^2/(4+x^2);

Some time ago, I confronted the usefullness of the Table element of Maplets, and found out it was something marely to show data that was known on design time, no posibility to dinamicly inject data on it for example on a result table after a process, but in the past days I met MatrixBuilder, on the Student, LinearAlbegra package, and I wonder first if that is a maplet, and second, if that is a table element, I tried to crack on the source code of it, but no info came out.

Someone knows what is this window? or if someone is able to crack the source can show me the table part?

I am trying to import data from Vernier's LabQuest for curve fitting in Maple 11. I can get a .CSV file which appears to be loaded in Maple  11 but I cannot get it in a format that I can use the polynomial interpolation command. Is there a step-by-step instruction set somewhere that I can follow that will walk me through the import to final polynomial fit? The data is titration data with over 1000 pairs of data ... way to much to imput by hand.

Thanks for any help.

I'm optimizing a procedure so that it can work as fast as possibly can. 

How do I find out how long it takes for maple to make a calculation?

I did evalf(3^1000000,1000) or something like that on a laptop.  It was taking a long while so I pressed the interupt (stop hand) button.  Nothing happened, it didn't stop.  It did finish what it was doing but it didn't immediately stop.

Unless it was trying to update the screen with all the numbers I think maple should have just stopped whatever it was doing and give me back control.  

Is there an equivalent Maple command for the "angle" command in Matlab?

I'm trying to get the phase angle out of a complex number.

Thanks.

If you're writing an external library to be called from Maple, then you have the following problem. The user wants to interrupt your code. They are valiantly pressing control-C or the stop button in the Maple GUI, as your code grinds their machine to a halt. What do you do ?
