The following link points to a worksheet located at the Maple Applications Center. It looks like it will do what you want, with repeating waveforms. You must be a registered user in order to access it. Registration is free. http://www.maplesoft.com/applications/app_center_view.aspx?AID=2035 Regards, Georgios Kokovidis
Try this: >restart: >with(student): >slope([22,100.19],[95,600.19]); >?slope for more information and the proper way to call this function. Ideally, you should fit your line with a function, and then take the derivative of that function. The above will give you the slope from a pair of points. Notice that there is one set of brackets surrounding the pair of points. Regards, Georgios Kokovidis
Look at the link below from the Applications Center. It does exactly what you are asking. http://www.maplesoft.com/applications/app_center_view.aspx?AID=978&CID=10&SCID=148 Regards, Georgios Kokovidis
The following is from the help pages for sqrt: Note: Maple does not simplify sqrt(x^2) to x. This is wrong for negative x. Maple returns (x^2)^(1/2). Sometimes, because of the context of your work, you know that this transformation is valid. If the symbolic option is specified, and signum(x) is not known, then sqrt applies transformation (7), effectively assuming that x is positive. Note, it is also possible to force the sqrt function to make a simplification by making the appropriate assumption, for example, assume(x>0). See ?sqrt for more details. This may answer you question, or add more doubt. Good luck either way. Regards, Georgios Kokovidis
As a starting point, take a look at the link below. It is a worksheet from the Maple Applications Center. Register to login in and then download the worksheet. In general, post worksheets or code from worksheets. Not to many people will open a Word doc or any other document for that matter and try to type in what you have in that document. If I can cut and paste your code to evaluate it, then I can try to help. If I have to start from scratch, then it depends on whether or not the particular problem is of interest to me. Like everybody else, time is limited. Hope this link helps. http://www.maplesoft.com/applications/app_center_view.aspx?AID=1919 Regards, Georgios Kokovidis
?unapply at the Maple prompt. Regards, Georgios Kokovidis
>restart: >x:=[3,4,5]; >f:=x->sin(x); >map(f,x); >evalf(%); You can avoid the call to evalf by making the original list of numbers floats, as follows: >x:=[3.,4.,5.]; >f:=x->sin(x); >map(f,x); A simple direct approach is to combine map with the function directly. >map(sin,x); Depending on how x was defined, you will get an answer in floats or a symbolic version.

Finding a more "comprehensive" manual than the one written by Maple might be tough. I prefer to download worksheets that others have created from the application center and study them. I execute them line by line and look at the results. Then I modify them and see what happens. The guide below is from the application center. You have to login in ordere to access it. http://www.maplesoft.com/applications/app_center_view.aspx?AID=1864 Regards, Georgios Kokovidis
Click on Tools-Options-Display and look at the first checkbox. It says "Automatically display legends in 2-D plot". Uncheck that box and see if your problem goes away after you re-execute your worksheet. Regards, Georgios Kokovidis
A good starting point would be the help page associated with the command for solving differential equations. There are examples there that you can cut and paste into your own worksheet, to solve your specific problem. You can also follow the links within the help page to take you further along with other methods for a wide variety of solution techniques, depending on the problem at hand. At the Maple prompt, type ?dsolve and hit the enter key. >?dsolve If you have a particular problem that is alluding you, post it here. Otherwise, try some of the examples in the help page and see how they work. Regards, Georgios Kokovidis
See the Statistics package and more specifically the fit function within the Statistics package. >?Statistics for more help. The link below is from a previous post that sounds similar to what you are trying to do. http://www.mapleprimes.com/forum/surface-fit-with-boundary-conditions Regards, Georgios Kokovidis
>restart: >assume(z,complex); >sol:=solve(3*(z)^2-1 <= -abs(conjugate(z))^2,z); sol := RealRange(-1/2, 1/2) Regards, Georgios Kokovidis
Try allvalues: >allvalues(%); Regards, Georgios Kokovidis
>restart:with(plots):with(Student[Calculus1]): >f:=abs(x^3-2*x^2+1); >plot(f,x=-2..3,y=-1..4); >ExtremePoints(f,x); >evalf(%); The answers given are the x-coordinates that satisfy the min and max for your function. For more help, see ?Student[Calculus1] Regards, Georgios Kokovidis
>with(plots): >implicitplot3d(cos(.5*x)*cos(.5*z) +cos(.5*x)*cos(.5*y)+cos(.5*y)*cos(.5*z)-0.5=0, x=-Pi..Pi,y=-Pi..Pi,z=-Pi..Pi); Regards, Georgios
