Yes there is a workaround for 13 and older.  See the link in the replied answer above.  By introducing a secondary pde the correct solution is obtained. :)

 

 

Similarily with two lines I would not expect to have to assume anything

with(geom3d):
line(l1, [a1*t+x1, b1*t+y1, c1*t+z1], t);
line(l2, [a2*s+x2, b2*s+y2, c2*s+z2], s);

distance(l1,l2)

Error, (in geom3d:-distance) unable to determine if two lines are parallel or skew

I expect

    (b1c2-b2c1)(x2-x1)-(a1c1-a2c1)(y2-y1)+(a1b2-a2b1)(z2-z1)
d= ---------------------------------------------------------------------
     sqrt[ (b1c2-b2c1)^2 + (a1c2-a2c1)^2 + (a1b2-a2b1)^2

There may be a third part program that could do that, but not in Maple.  The third party program I had in mind was hotkey bind, but then I'm not sure that program can do that.

Otherwise selecting with your mouse and using the usual crtl-c crtl-v will have to suffice.

crtl-l can select the evaluated input (output) but not the actual commands for the input.  I had a similar question a long time ago about recalling the commands that produced a certain output. 

Suggestion to Maplesoft - CRTL-SHIFT-I  could be a shortcut key to enter the last input .. might be a handy little shortcut for Maple

 

This code is quite a bit longer.  Your values wrap around the screen so I used a smaller sample just for illustration purposes.

b := []:
c := []:
for h from .01 by .1 to .5 do
  AA := (1+h)/h^2:
  b := [op(b),h]:
  c := [op(c),AA]:
end do
printf("%a \n %a", b, c);

rhs(sol[5]) will provide you with what you need.

Maybe this will help

Create a combo box and use a command like to create a list in the box

DocumentTools[SetProperty](ComboBox0, itemList, [1, 2, 3, 4, 5]);

Does it occur in both classic and standard interfaces? 

That has never happened on me before XP.  This is a Windows 7 problem for sure.  Try using compatabilty mode in windows 7 for Maple12 that could fix your problem. 

 

From the windows website:

 

1. Right click on the program's shortcut (LNK file), .EXE file, BAT file, CMD file, or MSI file.

2. Click on Properties.

3. Click on the Compatibility tab. (see screenshot below)
NOTE: If the Compatiblity options are grayed out, then it is a 64 bit program and cannot be changed.

As you say you are running a 64 bit version so you may be out of luck.  But Windows 7 is your problem.

Although the answer is already given an alternate way is...

interface(plotdevice=char)  # changes to plot in ascii art

interface(plotdevice=inline) # is the default

 

 

 

Thanks to you both, the plot in the proc is what I was looking for.

I didn't look into it too much but maybe this webpage will of some help http://www.math.sunysb.edu/~scott/Book331/Art_Phugoid.html

A bezier curve with these points (3,5,4) (2,8,1) (7,6,4) (0,3,2) would look like this

with(plots);
x := t-> x0*(1-t)^3+3*t*x1*(1-t)^2+3*t^2*x2*(1-t)+x3*t^3;
y := t-> y0*(1-t)^3+3*t*y1*(1-t)^2+3*t^2*y2*(1-t)+y3*t^3;
z := t-> z0*(1-t)^3+3*t*z1*(1-t)^2+3*t^2*z2*(1-t)+z3*t^3;

x0 := 3; y0 := 5; z0 := 4;
x1 := 2; y1 := 8; z1 := 1;
x2 := 7; y2 := 6; z2 := 4;
x3 := 0; y3 := 3; z3 := 2;

spacecurve([x(t), y(t), z(t), t = 0 .. 1], axes = box);


 

You can adjust the font size.

Select the whole table -> select format -> Character -> attributes   and change the font size to something smaller than the default 12.

Without knowing exactly what's in your table but guessing it probably consists of text and equations changing your font size should get exactly what you need.
