What is the mistake in this command ?

chfonc:=cat('piecewise(' , seq(cat(convert(t<lf[k],string) , ' , 1 , ' ,convert(t<lf[k],string), ' , 1 , ' ) , k=1..p) , '1) ') :

scatter2d  quantile2 scatter1d is removed?

with(stats): with(statplots): with(transform):
with(random): with(describe): with(plots):

who(things) replace it?

I hope someone can help me.

I'm trying to integrate the following equation:

The boundaries are

The exact command I'm using is


Suppose that S1,S2,S3 are 3 blocks of a matrix S := Matrix(...). I would like to do


out := ArrayTools:-Concatenate(2,convert(S1,vector),convert(S2,vector),convert(S3,vector)):

but in the case when I have n blocks.




I am aware of how to plot the feasible region defined by a system of linear inequalities (inequal in the plots package). Also, I can use the implicitplot command to plot the feasible region defined by a single nonlinear inequality. My question is, how do I plot the feasible region defined by a system of nonlinear inequalities. For example, how would a graph the region satisfying x>=0, y<=exp(-x), and y>=x^2?

I hope someone can help me.

I've tried evalf and simplify, but none of those worked. Does someone know how to solve this one?

I have program in txt,I want to copy it into the command-line maple 15 as belows:


How to do it. Ctrl+V is useless

> MEMBER := proc(x::anything, L::list, p::evaln) local i;

> if nargs>2 then p := i end if;
> RETURN(true)

Hi all,

I am trying to check a conditional statement in maple, I know it is true but my teacher has us do the entire assignment in maple. I am proving the alternating series test of convergence for a series and need to show that the Un's are all positive so


I am trying to check this statement for truth:


5/sqrt(x+4) > 0 for all real values x > 1

I run Maple 15 on an Acer laptop with Windows 7 and have the following problem:

When my Maple documents become "too" long, some of the vectors I have created seem to become tables instead (without me doing anything) rendering vector multiplications and additions/subtractions impossible (they'll throw an error; something like it not being possible to multiply a vector and a table. As if one of the vectors in my multiplication has become a table). Should it...

Can maple solve this kind of inequality:
piecewise(x > k, x-k, 0) > q * piecewise(x*(1+a) - k > 0, x*(1+a) - k, 0) + p * piecewise(x*(1+b) - k > 0, x*(1+a) - k, 0)
where p, q, a, b, k are parameters?

I'm trying solve-command with allsolutions option but it doesn't work :(


Thanks for answering :)


How can I use loop-varible in a definition of piecewise function? For example, when I do:

for k to 5 do

f[k] := x -> piecewise(x > 0, k, 0);

end do;




I get:

f[3](1) = 6

f[2](1) = 6

Hi everyone,


I would like to do:

Basically it is to define j(f(x))
But this is doesn't work. What is the right way to do it?\
My final goal is to calculate int(j(f(x)), f(x)=-infinity..infinity).

I have the following lines of code:




for c from 0 to 2 do

  for d from 0 to 2 do


  end do

end do;


I mean to compute the coefficients in front of powers of e inside...

I more than 20000 data points on a an excel file and i want to plot one column against the other. So I imported 10 data points from each column seperately and tried ploting it as a normal plot but it would not work. I kept on getting error messages like 


Error, (in plot) incorrect first argument [Array(1..10, 1..1, {(1, 1) = 0.83333e-2, (2, 1) = 0.166666e-1, (3, 1) = 0.249999e-1, (4, 1) = 0.333332e-1, (5, 1) = 0.416665e-1, (6, 1...

Like this! Some error. How to do it
