## How to convert expression to sum?...

I get the maple result as a product and sum off terms

x= (a+b*c)/d

i want to convert it to

x= a/d+b*c/d

i try to use convert(x,?)

## Decimal inches to fraction...

Is there a built-in Maple function to convert decmial inches to inch fraction. For example 1.74 as 1+3/4 ?

Trival to do in Delphi or c++ or even create a Maple function. However I would rather use a built-in function.

Thanks

## How to reserve the form of a number?...

When executing the following orders,

a:=0.006:

convert(a, symbol);

the result is .6e-2.

How to make Maple return the form 0.006, just as the original?

## How to convert to matrix over finite field?...

Hi all

I need to convert int matrix into matrix over finite field.

E.g: Convert inform integer number

A := <140, 155, 162, 64;

218, 12, 245, 50;

36, 251, 34, 253;

171, 251, 184, 37>;

into B = <x^7+x^3+x^2,x^7+x^4+x^3+x+1,x^7+x^5+x, x^6;

x^7+x^6+x^4+x^3+x, x^3+x^2, x^7+x^6+x^5+x^4+x^2+1, x^5+x^4+x;

x^5+x^2, x^7+x^6+x^5+x^4+x^3+x+1, x^5+x, x^7+x^6+x^5+x^4+x^3+x^2+1;

x^7+x^5+x^3+x+1, x^7+x^6+x^5+x^4+x^3+x+1, x^7+x^5+x^4+x^3, x^5+x^2+1>;

(Matrix B over finite field GF(2^8)/f(x) =x^8 + x^6 +x^5 +x^3 +1)

Thanks alot.

## Translating Maple to Mma...

Occasionally I have need to import 1D Maple expressions into Mathematica, because I believe mma has superior simplify functionality (sorry Maple). Mathematica has its own syntax which (of course) differs to maple.  eg sin(x) in maple is Sin[x] in mma ; ln(x)=Log[x] ;....... I'm aware of the package MmaTranslator, but I think it only converts mma to maple.

so i need some code pls.

(i have bolded the functions which need to be converted)

eg: i/p:

(1/365)*(365*B21*EP*ln(1+i)*(1+i)^B21*hr*kw*p-365*EP*hr*kw*p*(1+i)^(-1+B21)*i-365*EP*hr*kw*p*(1+i)^(-1+B21)+365*EP*hr*kw*p+SC*i)/(hr*kw*(EP*ln(1+i)*(1+i)^B21*p-FIT*i*p+cos(omega)))

o/p:

(1/365)*(365*B21*EP*Log[1+i]*(1+i)^B21*hr*kw*p-365*EP*hr*kw*p*(1+i)^(-1+B21)*i-365*EP*hr*kw*p*(1+i)^(-1+B21)+365*EP*hr*kw*p+SC*i)/(hr*kw*(EP*Log[1+i]*(1+i)^B21*p-FIT*i*p+Cos[omega]))

## Convert doesn't work with label?...

Hi guys,

I can not convert a series with label.

If anyone can confirm this?

## How to obtain this representation?...

It is given

xn (n x - n - x) / (x-1)2 + x / (x-1)2  , n is a (symbolic) positive integer.

I want to transform it into

n xn+1 / (x-1) - x (xn-1) / (x-1)2

How is it possible?

I tried the  simplify, convert (parfrac), collect, combine, expand,  with/without assuming.

## Remove the box in export as eps...

Hi all

I have  a simple question in export as eps format in Maple. i want the converted eps file with no box, but when i use export as eps by right click on plotted figure in Maple and then select " Export As--> Encapsulated PostScript(EPS)...", the below mentioned box(as in sample attached picture) will appear. How can I remove it? The Sample picture is attached.

## How to convert string input to symbol?...

I run the following working maplet:

Where "muutujad" is a procedure I defined and which returns the three inputs in the form [TF1,TF2,TF3].

It works fine, but if I insert "theta" as input, it of course stays in the string form, not Θ. Even if I copy the symbol and paste it in the textfied, it doesn't accept the symbol. Is there any way I can convert the text input to actual symbol?

## How to convert vector to matrix? ...

I have a vector of dimension n with each component being an equation of a linear system.

Can maple convert this Vector to a Matrix-Vector form with the matrix being constant coefficients?

## how to convert continued fraction?...

we can get the continued fraction of cot(x) with the command

> convert(cot(x), confrac, x, 6)

the result is

(1+x^2/(-3+x^2/(5-(1/7)*x^2)))/x

how could I convert this result to a form like

1/x-(1/10)*x+49*x/(20*x^2-210)
