Hello. I'm having a problem graphing the following parametric equations in 3d , together: x=1-2*t y=-t z=3+t and x= 5+3*s-4*t y=7-5*s-5*t z=-2-s+6*t Thanks, excuse-me my English, I’m foreigner

Hallo, I have a function in form f(x(t)), how can i define it in maple and diff it? thanks a lot ex ante.

Hi, Thanks to a few matrix-transformaties, I have elements like ' 1/2*cos(t)-1/2*3^(1/2)*sin(t) ' which also equals cos(t+1/3*pi) (--> thx to: cos(pi/3) = 1/2 and sin(pi/3) = sqrt(3)/2). But I don't find any way to make maple realize that it can be simplified that way. Can he make such simplifications? thx in advance

How do I use newtons method tutor to find the fixed points of a function?

Ok, I'm writing a procedure that will return either true or false as to whether a given coordinate (u,v) lies with the plane polygon, made up of n sets of points (xi,yi). I can write the loop code (I think) to check whether u and v are within the intervals; what i cannot do is define the matrix properly that representsteh points. I think it should look like: A:=linalg[det](linalg[Matrix](3,3,[X,Y,1,x[1],y[1],1,x[2],y[2],1])) Obviously this is for a 3x3; I want to replace the x[1], y[1] with i's; however, no matter which way i do this i get an error message saying that i have invalid parameters for a matrix.

Hi Maple experts, I have a seemingly simple procedure that is supposed to create random matrices. What surprises me is the fact that it takes more CPU time evertime I call it (even in a fresh session). The procedure is as follows: Feynman_random_rho := proc(N::posint, d::posint:=2)::'Matrix'(complex[8]); # # returns a random N-qudit density matrix where the optional second argument, d, # specifies the dimension of each subsystem. By default, d=2 is assumed so that # an N-qubit density matrix is generated. # The density matrices are uniformly distributed according to the Hilbert-Schmidt

Hello, I'm trying to integrate (for a homework) the Planck radiation formula. But the result (see the Maple10 worksheet below) is so strange (polylog(4,exp...) stuff) that I can't figure out what it means. I tried to compute taylor series at T=0 (because the exercise is to prove that integral is proportional to T^4) but Maple can't do it.

If i have this matrix in maple, what does it mean the last row (0 0 0 0 1) and what is 1? Is it like 2a+5b-6c+2d+6e=1. View 6573_problem.mw on MapleNet or

Hi! I am trying to write a question involving a second order initial value problem. The 2 conditions are u(0) = $a du --(0) = $b dx but I am not able to code it correctly. I have tried ... $eq2=$mathml("(d^2u)/(dx^2)+($mamb)(du)/(dx)+($ab)u=0"); $eq3=maple("printf(MathML:-ExportPresentation(u(0)=$a))"); $eq4=maple("printf(MathML:-ExportPresentation(du/dx(0)=$b))"); ... This works fine for the first condition, but I get du ---- = dx(0) for the second one. Is there a way to get the "(0)" in the right place, either using "$mathml" or "printf"? Thanks in advance for your help.

So I put in my first line and hit return. Maple spits out the second in which my 47.3 lbs/ft^3 gets turned into SI units while the other two quantities are left in FPS. Can someone tell me why?

Is there a way in Maple to compute the symbolic upper bound and lower bound of a given symbolic formula? Thanks. Bo

I have no idea what LaTeX, is other than a helpful tool for publishing. However, I'd like to start using it for several reasons, but don't know where to begin. Can anyone suggest a very first starting point for someone in my position ? v/r, Thanks,

I'm new to Maple. I'm quite competent with Matlab, with competent meaning I have some experience using it for analysis of physical data. I'm very experienced in using my TI-89 Titanium I have decided to give Maple a try since I'm not satisfied with the way Matlab handles symbolic expressions. I also want to tryif there's anything better than Matlab. I'm majoring in physics, and I hope to get my bachelor degree in a year. So far I have been writing all my assignments that needed a computer in Microsoft Word, but that is far from satisfactory. I have been considering learning myself LaTeX, but I have been thinking if it's just as good to use Maple to write articles and documents. Can I write an article as fast in Maple as I can in LaTeX? Speed is key for me naturally. Can I write LaTeX directly in Maple?

I am writing a program in which, after some calculations, I want to give the user some information and then ask them if they want the program to continue. I've tried using readline(terminal) and readstat, but I have the following problem: the information that I want the user to see is printed at the bottom of the screen and Maple gives a dialog box to get the user input. With the dialog box showing, the user can't scroll down to see the data. Is there a way to make sure that the data shows up before the dialog box pops up? Or is there another way to get input from a user?

I was wondering if I could change the values on the x-axes. I want to have the value 3500 at origo and 0 at "3500" normally is, can this be done?
