> int((x^2+1)^3/2,x=0..1); gives 48/35 as an answer. > int(((x^2 + 1)^(3/2)),x); gives me a symbolic answer that is identical to what I get in Mathcad. Regards, Georgios Kokovidis Dräger Medical

Try this: Notice the multiplication sign in between the x's. When using the display command, do not include an semicolon at the end of the variable assignment. Use a colon instead. > restart: > with(plots): > g1:=plot(3*x^2,x=0..10,y=0..10): > g2:=plot(10*x^2,x=0..10,y=0..10): > display(g1,g2); Regards, Georgios Kokovidis Dräger Medical

The results with Maple 10 and Maple 11 are the same as what you have above. Regards, Georgios Kokovidis Dräger Medical

I looked them up to see how fast they grow. I used x=500 because I new that 496 was a solution. I did this for illustrative purposes only. This is similar to searching for primes. You would not do this on your own using a laptop, as I usually do when solving Maple related problems. Regards, Georgios Kokovidis Dräger Medical

Maple does not have info on perfect numbers in a direct fashion, but if you ask for help on a perfect number: >?perfect number you will see that it points to a link for the sigma function. You can get to this directly like this: >?sigma function From here you can create your own function to test whether or not a number is perfect or not. >with(numtheory); >x:=500; >for k to x do if sigma(k) = 2*k then print(k) end if end do; Regards, Georgios Kokovidis Dräger Medical

For cryptography, according to the help page for rand and some of the sub packages, one should use the Blum, Blum, and Shub algorithm. At the Maple prompt, type the following for the associated help page. >?RandomTools[BlumBlumShub] Regards, Georgios Kokovidis Dräger Medical

This command is used for making a new function from a symbolic expression. That way you can pass the function a variable and have it evaluated. See the example below: >restart: >f1:=x^2+3*x+4; >f1(5/2); >eval(%); >f2:=unapply(f1,x); >f2(5/2); Regards, Georgios Kokovidis Dräger Medical

I have Maple 11 start up with "Maple Input" as the default mode. Under Tools-Options-Display 1st tab down the list you will see a selection for Input Display. I have Maple Notation selected. For output I have 2-D Math Notation. This way Maple 11 starts up looking as close to the Classic Interface as I can get it. Regards, Georgios Kokovidis Dräger Medical

The Maple dictionary defines it as: an expression for a given function or quantity, especially an integral, in terms of known and well understood quantities, such as the evaluation of Int(exp(-x^2), x=-infinity..infinity)dx as sqrt(pi). Two examples below that illustrate a closed form solution and one that does not exist in "closed form". >restart: >Int(exp(-x^2), x=-infinity..infinity)=int(exp(-x^2), x=-infinity..infinity); >evalf(%); >Int(x^x, x=0..1)=int(x^x, x=0..1); >evalf(%); A google search on 'closed form solution' yields many links that offer more information on this topic.

A copy of the share library for Maple version 10 and later can be found here. There exists a command called intsolve in Maple 11 but not in Maple 10. If you have Maple 11, you can get help for the command by typing ?intsolve. Regards, Georgios Kokovidis Dräger Medical

From a previous posting: http://www.mapleprimes.com/forum/excel-to-maple10 Hope this helps. Otherwise we can explore other options. Regards, Georgios Kokovidis Dräger Medical

I do not know how to create a Maplet, but as far as lines for geometric objects are concerned, there are many ways to do this. Below is an example where I used the features of the geometry package to create the line segments, and then plotted them one by one using the display command. If you right click on the plot, you can run the animation. Your Maplet can have the user enter a set of coordinates for the points, and you can pass these as arguments to the "point" command. This may or may not be useful to you. > restart:with(plots):with(geometry): > point(A,0,0),point(B,0,1); A, B > point(C,0,1),point(D,1,1); C, D > segment(l,[A,B]); l > segment(m,[C,D]); m > f1:=draw(l,axes=none): > f2:=draw(m,axes=none): > display({f1,f2},insequence=true); Another command that might be useful is "line" from the plottools package. Take a look at the help page for more details. >?plottools[line] Regards, Georgios Kokovidis Dräger Medical

Browse over to the main Maple web site here and in the search box on the top right, enter one word "ToolBox" and see what comes up. The bottom line is that these are add on products that can be purchased. From the marketing blurb: The Maple Professional Toolbox Series is a Maplesoft developed set of products that target key applications in engineering, science, and technical application development.

From your previous posting, and Acers' response, look at the help page for solve/details. There you will see examples that are exactly like the types of trig problems that you are trying to solve, with all ranges visible, if that is what you are looking for. >?solve/details Regards, Georgios Kokovidis Dräger Medical

Not a bug. Try this code below. The range will determine how many answers are returned. As you will see they match your calculator. >restart: >with(Student[Calculus1]): >Roots((sin(x))^2/x,x=0..10*Pi); Regards, Georgios Kokovidis Dräger Medical
