#### QUESTION

Is there a simple way to copy mathematical expressions between *Mathematica* and *Maple* (or at least in one direction)? I mean only expressions built from numbers and predefined mathematical functions, whithout any patterns or programmatical constructs like `Function`

, `Map`

or `Nest`

.

Ideally, I want functions with different definitions to be automatically adjusted, for example the *Mathematica* expression `EllipticF[Pi/6, 1/4]`

should be converted to the *Maple* expression `EllipticF(1/2, 1/2)`

.

#### ANSWER

I assume you have Maple to use. If so, Simply open Maple and type the Mathematica command itself directly into Maple using the `FromMma`

package built-into Maple, like this:

```
restart;
with(MmaTranslator); #load the package
(*[FromMma, FromMmaNotebook, Mma, MmaToMaple]*)
```

and now can use it

```
FromMma(`Integrate[Cos[x],x]`);
```

One can also use Maple `convert`

command with the `FromMma`

option, like this:

```
convert(`Integrate[Cos[x],x]`, FromMma);
```

For your example:

```
FromMma(`EllipticF[Pi/6, 1/4]`);
```

You can also use a Mathematica computational expression, not just single commands, like this, and then use the resulting Maple command inside Maple:

```
r:=convert(`Table[i,{i,10}];`, FromMma);
(* r := [seq(i, i = 1 .. 10)] *)
```

Now run the result in Maple:

```
r;
(*[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]*)
```

see http://www.maplesoft.com/support/help/Maple/view.aspx?path=MmaTranslator for information on the `MmaTranslator`

package.
