## algebra,factoring...

Maple 12

This is a simple algebraic, but I would like to know how to officially solve the problem,

I tried factor(6*a+12*b+18*c); it simply outputs what I input.

I tried primpart(6*a+12*b+18*c) ; the output is: a+2b+3c

I tried content(6*a+12*b+18*c), the output is 6

What I'm looking for an output is, 6*(a+2*b+3*c), this is the answer my Algebra book is looking for, I also get this answer by

using my HP Graphing Calculator, but I'm unable to get the answer from Maples. Can anyone help?

## How to plot two vectors of data?...

Maple 12

Hoe do you plot two vectors of data as a bar plot or historygram. I tried the statistics package but could not plot a bar plot that shows the proper relation of numbers in vector x to numbers in relation to vector y. Vector x contained years as data, and vector y contained for example crime data per year.

## How do I restrict input to a function or...

Maple 12

I have a formula, which is called the cube law. It requires input between 0 <= x <= 1. When creating  a procedure I run into all kinds of problems and get nothing but error codes. Trying to use assume works, it puts a tilde mark on the variable x, but doesn't restrict the input. Here is the formula the way it is writtin in a book on calculus:

f(x) := x^3/x^3+(1-x)^3 (0 <= x <= 1).

Trying to restrict the input to be restricted as required by the relational statement has been proven fruitless.

Any help would be greatly appreciated, thanks,

Rolf.

## How do I plot asymptotes to be shown in ...

Maple
When I am plotting functions with known asymptotes, they do not show, even though the text books show them.Also, I can use the Student Calculus1 Asymptote function to calculate that there is an asymptote, but when plotting, they don't show up.I perused plot/options but cannot find an option that I could enable/disable to have the asymptotes show in the graphs.

## Plotting range specifications...

Maple

Is it possible to include a step in the range when plotting a function? For example, plot(sin(x)-1/2,x=-1000..1000, in steps of 10) or similar syntax.

Your help would be greatly appreciated.

thanks, rolf.
