Maple 12.02 on a Mac running OS X.4.11.

As a first step trying to simplify a longish expression (pasted together from separate parts), I copy it to a scratch worksheet and ask it be displayed.  It shows up (2D Math mode) with the front part of it missing.  When I step through the expression with the arrow keys, the mode stays the same, so there doesn't seem to be break in it.  Here's the expression and its displayed form, pasted into the box that appears on clicking on the Maple leaf icon above this message input area:

Permutations...

Hi, assume we have two large nxn-Matrices A,B and we want to know if B is a Permutation of A, so A and B would have the same Elements, just in different places.
Because of the size of A,B, it has to be effective. What ist the best way to do this ?

Thanks

 

Hello,

how do I suppress printing of output in case the colon does not do what it should? Example:

if condition then
  printlevel:=0:
  printf("Some info...");
  gArr:=Array(1..2,1..1):
  gArr[1,1]:=plot(sin,-1..1,axes=boxed,color=blue,title=`Title 1`):
  gArr[2,1]:=plot(cos,-1..1,axes=boxed,color=blue,title=`Title 2`):
  printlevel:=1:
  display(gArr);
else
  ERROR("Error message...");
end if;

1,There are four points a=[3,4], b=[-4,-16/3], c=[-1,1],
d=[8,-8]. Write a simple program to find the intersection point
of straight line segement ab and straignt line segement cd.
 

2, Write a procedure to convert a list L into a set S?

thank you

I've used very similar code before, this time different equations, and for some reason getting the subscript selector thing, which Maple Help claims to have never heard of before.  I've been fiddling around with the code, and NOTHING gets rid of error.  PLEASE HELP!!

tryint to solve a series of d.e.

 

How do i plot both A & B on the same set of axes where

A={z:1<=|z+2i|<=2}; & B={z:1<=|Arg(z+2i)|<Pi/3}.

I'm struggling to plot A on it's own nevermind B!

restart; g:= x^2+(y+2)^2<=2; plots[implicitplot](g,x=-5..5,y=-5..5,y=-5..5,filled = true, scaling = constrained)

I'd have thought when |z+2i|=2 my circle should should go through the origin but with the above code it does not. Am i completely wrong here?

And how do i plot it with 1<= and >=2?

Any pointers would be very much appreciated.

Thanks

This is probably really simple and asked before, but a google search yielded nothing.
I just want to generate a table of results from a formula, so I can use and plot them elsewhere.

For example my graph is plotted with plot(function,x=0..0.75)
I just want 2 columns of data, one with the value of x increasing in intervals of 0.01 and one of the corresponding value of the function.

Thanks in advance

I don't even know where to start with this one:(

 Write a procedure PRIME_BRACKET that takes as input any positive real number (not just an integer) and finds the smallest prime number larger than or equal to the input.

How would I do the following?

1. Write a procedure MY_MAX to compute the maxiumum numerical number of a list L, which may contain ANY type of expressions. If there is no numerical number in L then return ERROR.

2. Write a procedure PRIME_BRACKET that takes as input any positive real number (not just an integer) and finds the smallest prime number larger than or equal to the input.

I'm new with maple and I can't seem to fix my problem. I want to enter in a textbox1.text in Visual Basic, a function -cos(x) for example- and calling a maple procedure to differentiate it and print it in textbox2.text

I've tried EvalMapleStatement and tried also to convert from maple object the result of diff() function with MapleToString.  

Maybe you can also tell me what sort of result returns the function diff(). VB recieves only some numbers that are different for every function I input in textbox1.text from what i've done here.

who can help me with following question?

Write a procedure MULTIPLYMATRIX to find the
multiplication product of an h x i matrix and an i x j matrix.

that is what I do. is it right?

mult := proc (A, B, C::evaln) local h, i, j; h := LinearAlgebra[rowdim](A); i := linearalgebra[coldim](A); j := linearalebra[coldim](B); A := array(1 .. h, 1 .. i); B := array(1 .. i, 1 .. j); C[h, j] := `&*`(A[h, i], B[i, j]) end proc

 

Is it possible to change the x_axis to an expanded scale for values less than zero, and keep the regular scaling for positive values?  In other words, display the x-axis from  -1 to 0 using all the real estate on the left side of the y-axis, and 0 to 10 on the right side.  Ratch

While looking at a Maple demonstration, it appeared to me that a intricate math expression was cut and pasted or dragged somehow into the text field, or next to a text field of a plot to become part of its documenation.  The demo went so fast.  When I try that, it does not work.  I can easily annotate the plot with text and math expressions if I type the math expressions manually, but I was hoping to bring the math expression in from somewhere outside of the plot.  Is that wishful thinking, or is it possible?  Ratch

hey everybody...i need your help

we have to define monotony interval of polynomial functions

i only managed to solve roots from the first derivative

does anyone have a clue ??
