If you take the results as part of some structure and break up the values of the x and y values into a list or Vector, then you can use the FrequencyPlot function from the Statistics package to plot the frequency of each. Scott

Could you post a simple worksheet that is showing this and the changes that you are making to the parameters? It appears that X and S are being set to variables pointing to a table, instead of left as functions. Have you defined something like X[inlet] or X with a subscript of inlet? If so, you are defining a table that is assigned to the letter X. Scott

What is Q in your expression? Scott

For the first question, you can find the solution in Maple by entering: solve(x*(2x+3)=-4); The results are -3/4+(1/4*I)*sqrt(23), -3/4-(1/4*I)*sqrt(23) For the second, you could try the following command: changecoords(x^2+y^2 = 4, [x, y], polar, [r, theta]); The result from Maple is r^2*cos(theta)^2+r^2*sin(theta)^2 = 4 which can then be simplified to r^2=4 Scott

To make the above suggestion even easier to read, try this: f:=x->exp(-x)*sin(x); plot(f(x),x=0..2*Pi); Scott

This error message does come up if you don't have a valid Maple License file. One case when this will happen is if you have not activated Maple 11 yet. If you haven't, then click on the activate button that comes up on that message. If you have activated and you are still getting this problem, it may be more complicated and you should contact Maplesoft Technical Support. They should be able to get you up and running. Scott

Hi Benzaid, This bug about dragging an expression onto a plot and that plot to be updated with a plot of the expression is a bug. Our developers are aware of this and they are working on a fix for this for the next update. Scott

One method that you can use is to define the three lines for the region that the observer can see. For a 2-D representation you would be looking at a triangle. The following worksheet shows some things you can look at. View 185_Intersection.mw on MapleNet or Download 185_Intersection.mw
View file details Of course some of the steps from the worksheet can be packaged into a function to make calling different scenarios easier. Scott

If you would like to collapse the either of the docks in Maple, you can do this by clicking the arrow head (or triangle) that is pointing to the side of the screen. For the right side, the arrow should be pointing to the right. On Windows, this arrow should be at the top of the dock but on the Mac I believe it may be at the bottom of the dock. Scott

For the 3-D equation of the cone, you would need to know the direction it is oriented. If the cone has a vertex at (a,b,c), opening in the z direction and having the base radius of R, the the equation is (x-a)^2 + (y-b)^2 = ((z-c)*R)^2. For the equation of the line you have a choice of two points or a point and a direction. For the two points it would be something like: r(t)= a + t (b - a ) While a point and a direction is r(t)=m*t+a In these equations the r, a, b are vectors of points and m is a direction vector.

One other method you can try when wanting to do the indefinite integration in the Standard interface of Maple 10 and 11 is that you can enter the function (in your example it is (4*x-3)^3) and right click on it. From the context menu, you can select 'Integrate'>x. Scott

The answer to your question depends on the version of TA that you are using. If you are using TA 3.0, then you will be able to go to the Gradebook and search one or all the assignments for "In Progress" assignments. In TA 2.5 I believe you would have to go through the gradebook looking for the student record that is open. Scott

Hi Yadaddy, The fact that you are using Maple 10 may be the reason why you are not able to see the other results that some other users have mentioned. Some of the new features in Maple 11 has to do with PDE and ODE solving (What's New in Maple 11). Scott

Luna Moon, what version of Maple do you have?

Here is a possible solution using an altered form from your earlier try: aa := proc (m, x::(Matrix(2, m))) local S, k; S := Matrix([0, 0]); for k to m do S[1] := S[1]+x[0, k]; S[2] := S[2]+x[1, k]^2; end do; S; end proc; bb := prep2trans(aa); cc := C(bb, optimized); As an aside from your last post, you should watch out that when you assigned 'aa:=x[1,k]', that the k here may not equal the k within the procedure. Unless you specified that the k in the procedure is global, then these will not be equal. Scott
