Hello,

If I have a function:

f(x):=x^2:

And I want

The array: f(x-y) for all x & y  from 0 to 2 with stepsize 0.5

in the same format that matlab stores saved arrays (in a .mat file), is that possible ??

Basically, I would like to be able to open matlab and load an array called 'f' 'from a file generated from maple, such that when I'm in my matlab workspase and type:

f

I get:

Hi,

I guess the best way if i give an example, what i would like to achive with maple:

q=5kN/m
L=10m
...
M=q*L/8=5kN/m*(10m)/8=62.5kN*m

How do i chek what order my procedure is . For example Bubble Sort is O(n^2) merge sort is O(n log n). I have a procedure but i do not know how to chek the order?

ODE:=theta'(t)=mu+sin(theta(t)); V(t):=cos(theta(t)); I need to Plot V(t) for various IC. An assumption I can make is mu

Hi all

I've launched a maple program (.mpl) with the syntax someone suggested to me here in the forum:

nohup nice -n19 maple <name.mpl> out.out &

on a pc to whom I've access through a ssh tunnel.

The code begins with the lines:

 

restart;

appendto("./garbage.txt");

... procedure declarations

... body of the program

END

 

 

Something strange seems to be happened, because the program hasn't accomplished all of his tasks.

Hi all I'm trying to obtain an expression for oscillatory motion in terms of the long-run amplitude, phase angle and frequency of a driven oscillatory system: deq:=diff(x(t),t$2)+lambda*diff(x(t),t)+omega[0]^2*x(t)=F[0]*sin(omega*t); The steady state solution I get from Maple is in this form ss:=((-omega[0]^2+omega^2)*sin(omega*t)+cos(omega*t)*omega*lambda)*F[0]/(omega^4+(lambda^2-2*omega[0]^2)*omega^2+omega[0]^4);

I need to numerically solve a 2nd order ode in maple and compare the numerically solved DE with the analytical solution by finding the error and plotting it as a function of time. I know how to solve the DE numerically in maple using dsolve(......, numeric), for example, sol :=dsolve({D(y)(t)=t^2-sin(y(t)),y(0)=1},y(t),type=numeric); and then out comes the solution as a procedure, sol := proc(rkf45_t) ... end sol(2); [t=2, y(t)=2.156829]

I have problem with following question:

"You are given two functions: h(x) = (x+2)^2 - 15x - 30 and L(x) = qx, where q is any real number. Find the value(s) of the parameter q such that the area of the region enclosed by these two functions is equal to 1000."

Here is what I have done so far:

1) declare (and display) both functions:

h := proc (x) options operator, arrow; (x+2)^2-15*x-30 end proc; L := proc (x) options operator, arrow; q*x end proc; plot([h(x), subs(q = 5, L(x)), subs(q = -25, L(x))], x = -20 .. 20, y = -200 .. 500)

I got this access file that I have mounted on the Microsoft SQLServer 2008 Express.
After a lot of problems (username, passwords, jarfiles, urls, jdbc drivers etc etc )
I have managed to get it to work (only blue text yippeieee) but when I run
Database:-QueryBuilder(connection) I get :

Error, (in Database:-QueryBuilder) could not get data for 'name', this option may not be supported with the current database system.

i have two lists, and i want to merge them together and then put them in order.
Can any1 help me?

Hello,

I have

-Copy

-Copy full precision

-Copy as MathML

-Why am I able to use whatever strange copy method I have the feeling is useless to me but no simple, plain Copy? Why? Why were you able to implement strange copy functions but not one like the simple one of Windows Notepad.exe's and whatsoever? Or what am I doing wrong?

I have been looking in Maple User Manual on how to create tables. It does describe how to do it manually going from cell to cell. What I am looking for is however a way to do it more automatically, like for example in Microsoft Excel, where you only need to write the formula in one cell and then copy down the formula to the rest of the cells in the actual column by dragging. I know Maple doesn't work the same way, I just want the proces automated ...

 

I've got a system of ODEs I need to solve for dependant variables phi(t) and a(t) with independant variable t.(appologies, it's a bit messy; the maple tag isn't making things render nicely)

dsys := {(D(D(phi)))(t)+3*a(t)*(D(phi))(t)/(D(a))(t)+dOm(phi(t), a(t)) = 0, a(1000) = sqrt(2*sqrt((8*Pi^3*(1/45))*To)*1000), phi(1000) = 12*M^(alpha+4)*alpha*g^2*sqrt(8*Pi^3*(1/45))*To^((1/2)*alpha-1)*10^(1/(alpha+2)), (D(a))(t) = sqrt(RhoDE(phi(t), a(t))+RhoM(a(t))+RhoR(a(t)))*a(t...

I'm trying to find out whether or not Maple V R5 can plot a polynomial with a specified area under the curve shaded.

Any other "old timers" here?
