Hey everyone,

   When I type ?command to view help pages, Maple always says "No Matches Found." For example, when I enter the command ?plot to bring up a help page on plots, Maple will say "No Matches Found."

How do I obtain the Maple help files?

Problem. write the equation of the line cut the two lines d1: x = 2*t, y= -t+1, z = t-2, d2: x = -1+2*m, y = 1+m, z = 3 and perpendicular to the plane 7*x+y-4*z=0. 

This is my code.

 Hi 

I am usign dsolve for maple to give my a fuction z(t) . Maple solves the differential equation but i want maple to give me the exact number for specific t values z(60) and so on. But maple is given as an answer z(60) and not a number

Hi,  if i have a matrix 4x4 as

A=[I          Y        -X        aX

     bY        Z         o          o

      X^T     O^T     0         0

       o^T  O^T       0         q ]   

With(geom3d), equation of  a line has the form a parametric equation. How  i can get canonical equation of a line? Please help me?

All critics and new ideas would be appreciated.

Hi everyone, I have a question:

In case if I assign for example:

x:=2:

y:=3:

z:=x+y;

Maple will print (output) solution in form :

What does error message in Title mean, and how can I cure it? (I cannot copy and paste from my .ws into thie question box).

I can't write a program to solve the following problem:

The first two terms of a sequence are a1 = 1, a2 = 1/sqrt(3). For n >=1, a(n+2) = (an + a(n+1))/(1-an*a(n+1)). What is a2012?

Hi

I'm working with some rather complicated functions in Maple. They are elements in matrices, and I need to perform mattrix operations on them, as well as integrations. When I try this with my complete functions, Maple locks up. Therefore I am trying to make approximations to some of the functions. The example below shows an example, where the complicated function (green) is denoted theta24. I comvert it to a 5th degree polynomial (red). But the approximation only...

I would see on the monitor the vector n > 10 with all his components, but the output of Maple is always the structure of the vectors.

For example, if I write:

Is it possible to paint in black and white colors the cells of 5x5 grid so that each 3x3 square contains exactly 5 black cells and  each 2x4 rectangle (vertical or horisontal) contains exactly 4 black cells? How to answer this with Maple?

Hi,    I have the following    

for i from 1 to 100 do    x[i]:=cos(θ[i]);     y[i]:=sin(θ[i])  end do; 

Now I want to find the first and second derivatives for x[i] and y[i] which are

for i from 1 to 100 do     x1dot[i]:=-sin(θ[i]);     y1dot[i]:=cos(θ[i]); 

                         ...

A very useful feature of the plotting program gnuplot is that you can generate an output which is a file instead of a graph. For instance the following short script

################
f(x)=sin(x)+cos(pi*x)
set samples 5000         
set table "outfile.dat"
plot [0:10][] f(x)
################

produces a  file containing a sampling of the function f(x) on the interval [0,10] based on a grid...
