## How to write mathematical expressions as...

Maple

Hi there,

Guess the title is already the full question. I want to write mathematical expressions in 2D math within a text segment of my Maple 15 document, but it should not be recognised as an execution group. How can I do this?

Cheers!

## How to address a specific case of an out...

Maple

Hi there!

I like to work with output labels, since it allows me to execute a lot of code without having to make sure the respective previous calculations already ran each time I open the file.

Say my output is a list, and has label (1.3), then I can address the 2nd element of that list by (1.3)[2].

Sometimes output is organised in cases, for example when solving for the root of an equation. How can I address a specific case of that output using the output’s label?

If the case specifier is simple enough I can do that with "assuming". But when it is more complicated it is quite cumbersome to do so.

Thanks for help!

## How to write simplify(eval(…)) as compos...

Maple 15

Hi there!

In order to keep the code more readable, and to spare myself some brackets, I am trying to use the function composition to write

as

but it doesn't work. How would I do it the right way? (I am coding in 2D math)

Thanks for help!

## Evaluation of a spline function is very ...

Maple 15

Hi there!

I wrote a piece of code which spits out the numerical datapoints (x,y(x)) corresponding to a function y(x). So that the result is accurate, I need quite a lot of data points - currently I am working with 5k.

In order to work with this function later, I interpolated it with a Spline. For instance, I would like to sample the function values on a fifferent grid, etc.. However the evaluation of this function really takes up hell of a lot of time, and the reason seems to be, that it, being a spline on 5k nodes, is simply a huge expression.

Is there a better way to do this? Are other fitting functions than a spline maybe better suited?

Thanks for help!

## how to tell maple that one variable does...

Maple 15

Hi!

Say, I got an expression that depends on two variables, x and y. How can I tell Maple, that y is actually just a (real) constant, so y does not depend on x?

Because when I apply a differentiation with the "D" - command, it would always also write out expressions, where y is differentiated w.r.t. x.

Thanks!
