Please see ?plot,details 6th example. You could do something like this; restart; L := [[ x, (-1)^x] $x=1..10]; plot(L,x=0..10,y=-3..3,style=point,color=blue); Hope this helps. J. Tarr
Which version of Maple are you using? Your example on differentiation works perfectly as it stands without any single quotes in both Maple 10.06 and 11.01. I am not sure what you want for the multiple integral, but you might find what you want in the help page at ?evalfint. Hope this helps. J. Tarr
If you want to obtain the arithmetic mean from your data, the first thing to do is to look at the relative frequencies of the data in the lowest and highest classes (categories). If they are small, then either omit that data, or pool them with the adjacent classes. On the other hand, if the relative frequencies are large, you have the classic problem - a poorly designed experiment and data collection. Short of doing the experiment again and collecting the data again, there is not much that you can do, but an expert on statistics from the mathematics faculty at Oxford might be able to help you salvage something. Hope this helps. J. Tarr
Do you mean something like this? restart; GAMMA(4 + I*5); evalf(%); Hope this helps. J. Tarr
You could try this: restart; eq := a^2 = (b^2*c^2) + (a*d^2)/(a-e^2); solve(eq,a); Hope this helps. J. Tarr
If you could upload your worksheet, someone should be able to help you. J. Tarr
A common problem is that Optimization used by NonlinearFit needs some initial values. The physics of your problem may suggest some values, but failing that you may need some inspired guesses. I was able to plot a curve that bore a passing resemblance to the image that you uploaded as follows: restart; f := a+b*w/(1+(w*(t-t0))^2); g := eval(f,{a=2500,b=57500,w=1/10,t0=365}); # guesses plot(g,t=300..450); Hope this helps.

Your post doesn't belong to this thread: you should have started a new one. How do you know that the parameters of the function you want to fit to the data are non-negative? For your second question, please see the help page for ArrayDims. Hope this helps, J. Tarr
Please see ?plots[densityplot] for the different ways of entering the arguments. Your second call to densityplot uses x= range, y= range which is correct for an expression, but not for the procedure called in the first argument. I believe the two right quotes delay plotting the procedure until it has been evaluated over the range specified. But someone else here should be able to give you a better idea. Hope this helps. J. Tarr
You could do this: d := 'd'; or you could do this: d :=unassign('d'); Hope this helps. J. Tarr
Welcome to Maple! It is not very clear what you are trying to do, but there are two ways that you can erase the result of using a tutor and then closing the tutor window. You can simply delete the worksheet which contains the result from the tutor by File Close>Close Document and don't save it. Alternatively, click in the plot produced in the worksheet by the tutor and then press Ctrl+Delete. Then place the cursor at the end of the command left by the tutor in the worksheet, and again press control+Delete. Hope this helps J. Tarr
I'm not sure what you are looking for, but perhaps the help page for Statistics[ChiSquareSuitableModelTest] is what you want? Hope this helps, J. Tarr
The plottools package might be able to do what you want, but I suspect it will be rather laborious. Hope this helps, J. Tarr
Please see the help page ?Map. Hope this helps, J. Tarr
The easiest way to import the dataset into Maple 10 is to save the Excel file as a comma separated variable (csv) file. Then do something like this: restart; A := ImportMatrix("C:\\path\\L3.csv ",source=csv): Hope this helps, J. Tarr
