Hi, was wondering if there is a way that i can integrate each element in my matrix?

N0:=zeta->Matrix([[-2*(1-zeta)*(zera-1/2)],[4*zeta*(1-zeta)],[(2*zeta)*(zeta-1/2)]])^%T   ###1x3 matrix

N1:=zeta->N0(zeta)^%T ###3x1 matrix

dot product of N0 and N1 is a 3x3 matrix

Can in integrate the 3x3 matrix? each of the element by zeta from 0 to 1.

Please advice. Many thanks. =D

Recently I've run into a strange problem logging into the MaplePrimes site.  I have two computers, both running Debian linux.  On one, I can login in using the FireFox browser.  On the other I cannot.  It accepts the password, but immediately reopens the window that prompts for a password.  If, however, I switch to the chrome browser on that machine, I can then login.  Any idea why Firefox (aka IceWeasel, on Debian) would have an issue?  Have I configured something strangely?...

I would like to see the contents of a .m file into a human readable form.  How do I do that?

Problem. Write the equation of the tangent planes to the sphere

x^2+  y^2 + z^2 -10*x +2*y +26*z -113=0

which are parallel to the lines

d1: x = -5+2*t, y = -3*t+1, z = -13+2*t

d2: x = -7+3*t, y = -1-2*t, z = 8.

This is my code

restart:

with(geom3d):

line(d1,[-5+2*t,-3*t+1,-13+2*t],t):

a:=ParallelVector(d1):

Dear all,

I am stuck with my gradient projection algorythm. I asked several questions on this but nothing helped.

So, the basic problem I have is the following:

I need to make a procedure, which would take as an input some function of time, x(t),

calculate numerical solution for the ODE system

diff(y(t),t)=f(t,x(t),y(t))->y_1(t)

via dsolve/numeric

then update the value of the function x(t)=f(y_1(t)),

giving as a result x(t...

I tried to find the list of hotkeys for Maple's commands but I found nothing.

Is there any hotkeys?

for example, It would be useful to have hotkeys for 'execute ALL toolbar', for Greek letters.

In MathCAD you write Latin analog + 'ctrl + G' and the programm returns Greek letter. for example to achieve 'alpha' you have to input a + 'ctrl+G'.

As many before me, ive lost all my note to this problem. Is there any chance to salvage this document or is it gone.

I hope you can help me

Let A(1,-2,3), B(-1,0,1) be two points and (P): x+y+z+4=0 be a plane. Write the equation of the sphere has center lies on the line AB, radius of sphere equal to AB/6 and sphere tangent to the plane (P).

This is my code.

Hi,

I'd like to draw a disk with center (0,0,0) , radius 1, in the plane theta=constant (or y=tan(theta) x), where theta is given different of 0.

How can I proceed?

Thanks.

i have a differential equation like below

with(DETools):

ivs3:=[y(0)=100,y(0)=250,y(0)=800]:

i tried to plot this diff equation but received an error message:

Hi,

I have ZeroMatrix(33)

How do I ask Maple to give me a big matrix form instead of just stating "ZeroMatrix(33)"?

[0 0 0 0 0 0 0 0 0 0.....]

[0 0 0 0 0 0 0 0 0 0.....]

[0 0 0 0 0 0 0 0 0 0.....]

There no curve on the second of the following two polar plots. Why? (I am using the 64 bit version on W7)

restart:

Let A(1,-1,-1), B(2,1,2), C(1, 3, 1) be three points and Delta: x = -t, y = -t, z = t be a line. Write the equation of the sphere (S), knowing that center of (S) lies on the line Delta, (S) passing the point A and cuts the plane passing through the  three points A, B, C cut (S) a circle has least radius.  

This is my code.
