## New to maple. How to simplify result?...

Hello,

I've just started to use Maple 16, and I can't seem to get a neat result, when I use the solve function to solve 4 equations with 4 unknown constants.

I've posted my calculations.

How can I get a simpler result? I found a simplification command, but that didn't help

## Combining two plots...

Hello,

does anyone know a way to combine two plots in one where one is created with ScatterPlot3D (Package:Statistics) and the other one with plot3D (Package:plots)?

Normally you would write something like this:

but that only works if the plots are from the same package...

## How to simplify it?...

I know that the following expression (a:=6*s*sqrt(9*s^2+32)+18*s^2+32)

can be rewritten as

However, none of the following maple functions is abble to give the factored result:

factor(a)

simplify(a)

combine(a)

Someone could help me to understand what is going on, please?

## Manipulating Series Equations...

How do I multiply the 4x into the summation to get    and same idea for the 3rd third?

Also, how do I go from     to    by manipulating the indices?

## How to combine 4 matrices in one ?...

a1 := Matrix(3, [1, 2, 3, 7, 8, 9, 13, 14, 15]);
a2 := Matrix(3, 2, [5, 6, 11, 12, 17, 18]);
a3 := Matrix(2, [19, 20, 25, 26]);
a2 := Matrix(3, 2, [5, 6, 11, 12, 17, 18]);

i want to combine above matrices in big matrix like

A := Matrix(2, 2, [a1, a2, a3, a4]);

best regards
