Problem. Write the equation of the sphere passing through the three points

A(-1, 2, 1), B(-3, 4, -5), C(1, 2, -3) and its centre 

1) lies in  the plane (P): 2*x + 3*y -z = 0;

2)lies on the sphere (x-3)^2 + (y+1/3)^2 + (z-1)^2=1.

This is my code

Hello,

I solved an equation, and Maple returns two values.  Even though I said, assuming v1i>0, the solve command returnse this:

logically evalf(x^(1/10)); should return x^(0.1000...0), not x^(1/10). Or it's just case of other rule?

When I do the following command in Maple:

How can I create using Maplet a window that is not modal, so I could minimize or maximize it (I know what to do to make it resizable and that's not the question I would like to ask).

This simple example creates modal window with no minimize and no maximize button:

> with(Maplets[Elements]);
> maplet := Maplet(Window([]));
> Maplets[Display](maplet);

Is there an option to set for a Window or maybe I should change some settings in Maple 13 that I'm using ?

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):

line(d2,[-7+3*t,-1-2*t,8],t):

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

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.

Hi,

I work on a dynamic programming problem and I must used the result of a maximization function, but I can not

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

restart:

with(plots):

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.
