Hi,

I opened an older worksheet (from version 9 I think) and opened it in version 10. In the new version it produces different results.

In version 9 the solution found with the solve function included sinh and cosh terms. The new version uses their exponential forms. The expressions are now much bigger, but are probably the same in effect. However I would like to get the Maple9 behavior for this solution.

I have tried the convert (function,trigh) but that didn't result in the clean function I got in earlier version.

Any ideas?

Hi!

I want to set up a question where students first should do some calculation (p-values actually). Next step would be to see if this value is an element of intervals given by me. It seems reasonable to attempt constructing a multiple choice question, but there could be alternatives. In the case of a MC, the alternatives could be like the following:

1. <0.005

2. 0.005-0.01

3. 0.01-0.02

4. 0.02-0.025

5. 0.025-0.05

6. 0.05-0.10

7. 0.10-0.15

8. >0.15

Hi there :) I often need to plot datapoints, and then fit a curve in then. So far i did this with the [i]ScatterPlot[/i] command, and moddeled the function to the data with the Fit or Nonlinearfit command. In most cases this worked really great, but i would need some extras: ;) As far as i have noticed the Fit is only based on the datappoints. The Fitfunction doesn't seem to take care of x- or y-errors, drawed in with the data. So: Is there a way to take care of the x- and y-errors in the Fitting process? If yes, how?

When I right-click on a 387x387 Matrix my pointer turns into a processing indicator and the system sits endlessly.  Other than killing the maple server process is there a way I can instruct Maple to cancel processing and make it responsive again?

hi, I was wondering how I can plot a phasediagram for the Solow growth model which has k(dot) on the y-axis and k on the x-axis and that has arrows that point in the right direction above k(dot)=0 and arrows that point in the left direction below k(dot)=0 The code I use to plot k(dot) is: restart: y:=A*k^a: S:=s*y: BE:=(n+g+d)*k: k_dot:=S-BE; s:=0.7: A:=1: a:=0.3: n:=0.06: g:=0.04: d:=0.03: plot(k_dot,k=0..15,color=blue, labels=["k", "k_dot"]); works fine but I am missing the arrows....

Cheers!

You will find in the attach file work that I have done in this subject.  Everything works fine when the calculation is around x=0.  But if for example I want to do it near x=4, I don't come near the value that Maple give me.  But the plot loook OK.

Is it the definition of px and qx in the file that I don't define correctly?

By the way, if you know a simple application on that subject (simple), I will be glad to learn about it

Hi,

Is there something like

assume(a,'nonzero');

 

 

how could i tell maple that

a

is a nonzero constant?

 

Thanks

i got problem coz i dont understand nor know what command i need to type in maple, really need help,

Question:

Hi all

 

I have spend too much time trying to figure out why Maple won't solve this equation explicitly. Here is the code:

 

assume(0 <= s, 0 <= w, 0 <= t, 0 <= h):

diff(((w-s)^(1-t)-1)/(1-t)+(((1+r)*s)^(1-t)-1)/((1+h)*(1-t)), s);

solve(%, s)

 

It returns:

 

-(w-s)^(1-t)/(w-s)+1/(1+h)*((1+r)*s)^(1-t)/s

RootOf((w-_Z)^(1-t)*_Z+(w-_Z)^(1-t)*_Z*h-((1+r)*_Z)^(1-t)*w+((1+r)*_Z)^(1-t)*_Z)

 

Cheers!

Here is what I have done in Maple 11:

st:=taylor(sin(x),x=0,10):

sint:=convert(st,polynom)

sinr:=convert(taylor(sin(x),x=0,10,ratpoly))

plot([sin(x),sint,sinr],x=-6..6,-2..2,color=[red,navy,gold])

My question is how theoraticly do you convert a series into a rational polynom?

I'm trying to find the greatest common divisor of two functions with characteristic=7:

with(Algebraic):
GreatestCommonDivisor(x^4+x^3+4*x^2+4*x+5,x^3+x^2+5*x+5,'characteristic'=7);

This gives the answer as (x+4) which is a common divisor but it is not the greatest. From working by hand, I've found that (3x+5) is the gcd.

Why is maple giving the wrong answer?

I decided to repost this as the previous one went crazy.......

I'm trying to construct an iterative procedure NR1(f,x0,N) where f is a function, x0 is an initial estimate (which can be complex) and N the number of iterates.

Given:  x_k+1=x_k - f(x_k)/f'(x_k), k=0,1,2....,

Now for example by defining f:= x-> x^2-2 and inputting x₀=1 and N=10 i should be able to check that my procedure calculates sqrt(2) correctly.

This is what i've got so far.....

hi, i am new to this and when i start up maple 11 i get the following error : "Java Virtual Machine Launcher,  Could not create the java virtual machine"

i hope there is a solution to this because i have searched everywhere and i cant get the solution.
