Hi. It is be good to be with you after 4 years.

I want to ask about Curvefitting for Data. If I have a numerical data and i want to find a function in x and y for these data.

Hi Maple friends.

As per usual, I am unable to find the solution in Maple Help. Can someone please advice me on how to shade an area under a curve, preferably using the context menu, since that is what I prefer to use at this stage.

Thanks in advance.

i have a non linear equation that depends on three variables e, theta and z.

i have done calculations to calculate e while varying theta and z. theta varied among the vector [0, Pi/4, Pi/3, Pi/2] and z was varying between 1 and 20

when plotting my data it gives the following plot where z is represented on the x-axis and each curve correspond to one theta

 

i am currently able of fitting one plot to one equation i would like to fit the data points using the nonlinearfit function and to only get one equation for all the plots. is that possible in maple or not

 

After simulate the model of MapleSim, I can only know the curve of where I need to know about. I need the specific parameter(each point value), like a piece of sheet. How I can put it of in an Excel of Word?

the point given as follows:

x=[3,4,5,6,7]...

y=[7.42494922444550, 3.67768248674133, 2.52235142453921, 1.95610223891559, 1.61770309810016]

 

I have plotted the point and the output is like this:

how to smooth the curve and extend the curve longer 

 

please help me.....

 

 

 

Hello everyone, I need your help again. I've been trying recently to select different colors and other line options to different curves in the 2D plot generated by the algorithm attached to this message, but I've had no success whatsoever. I tried using the setcolors([]) option, but it didn't work.

Any help with that would be much appreciated.

I have to plot 4 vectors in one graph. I have the following structure:

plot(Vector([12, 12.5, 13, 13.5, 14, 14.5, 15]), Vector([1.622712644, 1.265443137, 1.028604736, .8605013333, .7352916667, .6386248233, .5618945274]), style = line, symbol = asterisk, color = blue)

and 

plot(Vector([12, 12.5, 13, 13.5, 14, 14.5, 15]), Vector([5.483608580, 4.289400489, 3.496793877, 2.933480578, 2.513320599, 2.188469637, 1.930230220]), style = line, symbol = asterisk, color = blue)

Could you help me to plot these two curves in one graph.

 

please help me to find a solution for this issue...

I would like to thank you in advance

Best regards,

It's obvious that the second one is smoother than the first one,I want to know how to make curves smoother in Maple 16.

Hey, I have a system of ODE and I can't draw it's phase curve. I tried to use DEplot and phaseportrait, but it doesn't work. Here is my system:

 dx/dt=x

dy/dt=ky              (k is a constant)

 

Here is my piece of code:

DE := [diff(x(t), t) = x(t)];

DF := [diff(y(t), t) = k*y(t)];

with(DEtools);

phaseportrait([DE, DF], [y, x], t = -5 .. 5, y = -5 .. 5, x = -5 .. 5, k...

Hey, I'm trying to plot the phase curve of the simple system of ODE, BUT it shows me an error which one I don't understand at all :)

Here is my code:

DE := diff(x(t), t) = x(t);
DF := diff(y(t), t) = k*y(t);
with(DEtools);
phaseportrait([DE, D], [y, x], t = -5 .. 5, [[y(0) = 1, x(0)], [y(0) = 0, x(0) = 2], [y(0) = 0, z(0) = -2]], y = -5 .. 5, x = -5 .. 5, color = black, linecolor = red);

Hello,

I am brand new, just joined in order to thank a member (gmm) for a publicly searchable MaplePrimes post I discovered in researching the origin of french curves. I linked to gmm's post in a blog post I wrote about the application of conic sections in the drafting of sewing patterns. I tried to send gmm an email...

I just encountered a very strange behavior when using DEplot. I want to generate a slopefield and solution curves. However, when I enter the command, only the arrows in the slopefield are showing. If I click on the plot where the solution curve should be, I see the outline of the curve. It's as if the curve isn't begin colored. I hope someone is able to replicate this behavior and suggest a fix. Thanks! (See attached file)
