## How to change the font style in the woor...

Dear MaplePrime's guys,

I would like that the font style of  all (new) worksheets I open are with 'style" "CMaple input" " Courier 20 "..

How could I modify the setting please? Any hint is more than welcome.

I am using Maple 16 (on a MacBook pro).

## How to use PlanePlot (after with(Student...

Maple 16

Dear Maple experts,

I would like to visualize the equation -3*x+2*y+3*z=0  and (with other color) 2*y+3*z =0. I used the following commands:

with(Student[LinearAlgebra]):
infolevel[Student[LinearAlgebra]]:=1:
PlanePlot(-3*x+ 2*y + 3*z = 0, [x,y,z], normaloptions=[shape=harpoon], showbasis);

But I do not know how to show at the same time the second equation (2*y+3*z=0 ).

How should I proceed? Any hint?

## getting parametric equations...

Hello Maple users friends,

I have two lines in the space (x,y,z) described by the equations in L1 and L2:

L1:= {4*x + 3*y + z = 0, x + y - z - 15 = 0}:

L2:={12*x + 5*y + 7*z -13 = 0, 9*x + y -3*z - 5 = 0}:

I would like the get the parametric (with z=t) equations P1 and P2 of the two lines..

I see the "form" of such parametric equations P1 and P2 using "solve"

solve(L1, {x, y}); solve(L2, {x,y});

but I do not know how to use those values to get my parametric equations P1 and P2 to continue with additional computation (area, volume etc).

Thanks for your attention and help.

## A straight line in 3D...

Maple 16

Dear Maple users,

i have a set of 2 Lines: L1 (determined by the intersection of plane x + y -1=0 and plane x - z - 1=0),

L2 ( intersection of plane x + y-7=0 and plane x-y+1 = 0 ).

which functions or commands of maple should I use "visualize" those 2 lines L1 and L2?

## create a table/matrix/array ...

I was trying to create a array or table with the following columns

3. sinus (x)

4. cosinus (x)

5. tangent(x)

for x= 0, pi/12, 2pi/12.. 2pi.

I was trying to use seq()

seq([(1*Pi/12*j),sin(1*Pi/12*j)], j=0..24);

but I cannot get something nicely "arranged" (like in a table or matrix) to export to latex.

could somebody give me a help..please?
