Attention Maple enthusiasts! It gives me great pleasure to announce Maple 2024! Maple 2024 brings together a collection of new features and enhancements carefully designed to enrich your mathematical explorations. Maple 2024 is the result of a lot of hard work by a lot of people, and there is far more in it than I can cover here. But I’d like to share with you some of my favorite features in this release.

AI Formula Assistant

The AI Formula Assistant in Maple 2024 is undoubtedly the feature that excites me the most, especially considering how often I’m asked the question: 'When will Maple include AI features?' This assistant serves as your new mathematical companion and will change the way you look up and enter formulas and equations. Driven by advanced AI technology, it presents a range of relevant options based on your search query. Alongside suggestions, you'll also receive detailed explanations for each formula and its parameters so you can select the one you need, and then you can insert the formula into your document at a click of a button, as a proper Maple expression.

NaturalLanguage Package

The Formula Assistant is built on top of the new NaturalLanguage package, which integrates powerful language models like GPT-4 and ChatGPT from OpenAI into Maple. With this feature, you can leverage large language models to process natural language within Maple. Ask the AI to explain concepts, provide additional details, find specific Maple commands, and more. Of course, since this is a Maple package, you can also use it as a basis to build your own AI-powered applications inside Maple. We’re really looking forward to seeing what you will do with it!

Argument Completion
We’ve had a lot of requests from people who wanted Maple’s command completion features to do even more, and I’m happy to say that Maple 2024 delivers. The new argument completion feature in Maple 2024 is poised to significantly enhance your experience with commands. For many users, including myself, not being aware of all the options a command takes is a challenge, often leading me to refer to help pages for clarification. With argument completion, that's no longer a concern. Just enter the command with the help of the existing command completion feature, then automatic argument completion takes over to guide you through the rest. Give it a try with the 'plot' command!

Check My Work

A personal favorite feature that's gotten even better in Maple 2024 is Check My Work. As someone who has tutored students, I vividly recall their stress before exams, often receiving emails and text messages from them seeking last-minute help. At the time, I found myself wishing the students had a way to check their work themselves, so we would all be less stressed! So I was super excited when we added the first Check My Work feature a couple of years ago, and am very happy that it gets better ever year. In Maple 2024, we’ve expanded its capabilities to support problems involving factoring, simplification, and limits.

Scrollable Matrices:
This feature will definitely resonate with many of the engineers in the Maple Primes community. If you're someone who works with worksheets containing large matrices, you've likely wished that you could scroll the matrices inside your document instead of having to launch a separate matrix browser. With Maple 2024, your wish has come true.

Color Bars

And finally, for those of you who appreciated the addition of color bars in Maple 2023 but wanted to see them extended to more 2D and 3D plots, you'll be delighted to know that this is exactly what we’ve done. We’ve also added new customization options, providing you with greater control over appearance.

This is just a partial glimpse of what's new in Maple 2024. For a comprehensive overview, visit What’s New in Maple 2024.

Any idea why parse("a", 'statement') doesn't return the value of the variable, but only its name?

Running the same command directly works.

Hello everyone!

I wanted maple to give me the conditions when my inequality is fulfilled. But maple gives me exactly the same conditions for x (x here as placeholder) >0 and x<0. That makes no sense. The conditions themselves for x>0 (x<0) are also contradictory and illogical. 

Can someone please explain the solutions or what is wrong? I assume that conditions for the inequality to be fulfilled are missing. But I wanted Maple to give me exactly these conditions. I always use the solve command for this.

Thank you very much!

Best wishes

I tried inserting contents of my worksheet here but for some reason procedure test2 does not appear. Therefore, here is a screenshot.

What I would like is for the call r() above to print out 3,2 and then 5.

Basically, I'd like to know how I can call a function that has default parameter values with a value that makes the function use the default parameter value.

In the code above, the variable r is assigned to the return value of test2, which is the function called "inner". The function inner accepts an argument "b" and calls the function "test" passing in this "b" as the second argument. If I don't pass any argument to "inner" then it defaults to Null, which then gets passed to "test".

I want this Null to force "test" to use its default value for parameter "b".

PS As an extra, why does it give a "not able to parse" error when we declare a local inside of a proc as above? Note that I have it commented out.

Hello

Beginning with a given real fraction, for example 1/12, I would like to find out the following information about its decimal number (here: 0.0833333...):

- decimal number up to period, here 0.08

- the period if exists, here 3

How to program that in Maple?

Thanks a lot for your help!

How 

Where does one find the python module "maple" used to access open maple as in https://www.maplesoft.com/support/help/maple/view.aspx?path=OpenMaple%2fPython%2fAPI ?

Hi:

In a plot title, I want  A^(1)(x) to appear - that is, the first derivative of the function A(x) with the "1" enclosed in brackets because that is the standard notation for derivatives of the special function A.

Alternatively, I'll be happy to use A'(x) - and I know that there are calculus characters on the pallet that are supposed to do that, but they all just become Diff and that is no good for other reasons.

So, here is the closest I've come:

Test:=plots[textplot]([3,3,typeset(A^[1],"(x)")]);

and that almost works, except if I change the [1] to (1), Maple tries to evaluate it as an expression and it disappears. If I change 1 to 2 it works fine, except I want the first derivative.

I've tried quotes, uneval, backquotes and all I get is an error or the quotes showing up as text.

Does anyone know how to do this?

Thank you.

I have the set A := {12, 17, 24, 28} and the set B := {358, 568}. I would like to do the combination (at least that is the name I think I should use) of the two sets to get the following result:

{12358, 12568, 17358, 17568, 24358, 24568, 28358, 28568}

As a bonus, if it's not too complicated, I would like the procedure to see that there are two numbers that have repeating number in them. In fact, the last two elements of the result, namely 28358  and 28568 has two 8. So those last two terms should not appear in the result. We should get only the 6 elements {12358, 12568, 17358, 17568, 24358, 24568}.

There are so many possibilities with Combination and Iterator that I am lost in how to do it. Maybe someone has had to do it before me and have an idea on how to do it.

Thank you in advance for your time.

 dV/dt = -(omega+mu)*V

For t=nT, 

 S(nT⁺)=(1-gamma) S(nT);

V(nT⁺)=V(nT)+ gamma* S(nT),

    how to plot the graph with this system of equations,impulsive points and initial conditions  

Hello. In our math lessons, we are laerning about monotonicity within different graph and hereby, we are also working with making a line, describing when the graph is increasing or descreasing (I have uploaded a picture along to describe). 

I havent been able to find any easy way to make a monotonic line within maple, where i dont have to draw them in. This is problematic and will end up taking me a long time in each assignment where its needed.

Suppose I have to solve _Z^2 + (epsilon - 1)*_Z - epsilon + theta=0. If I use the code

solve(_Z^2 + (epsilon - 1)*_Z - epsilon + theta, _Z)

I get the solutions  as -epsilon/2 + 1/2 + sqrt(epsilon^2 + 2*epsilon - 4*theta + 1)/2, -epsilon/2 + 1/2 - sqrt(epsilon^2 + 2*epsilon - 4*theta + 1)/2

But I need them as (1 - epsilon)/2 + sqrt((epsilon + 1)^2 - 4*theta)/2, (1 - epsilon)/2 - sqrt((epsilon + 1)^2 - 4*theta)/2

How to modify the code so that I get the roots in the more simplified form, as I have mentioned above. 

Please help. 

Hello,

How I can show that the value of psi 1 through method #1 is equal to that one in method #2?

is possible to verify by analytic results, not using and placing parameter's numerical values?

The link to OpenMaple/Python/Examples from https://www.maplesoft.com/support/help/maple/view.aspx?path=OpenMaple seems to be broken, but not sure where to report such an issue.  

I've been writing this code to simulate the orbit of Venus in a simple 2D polar plot, but it keeps telling me that I have insufficient initial conditions, here is the code:

restart:with(Physics):with(VariationalCalculus):with(plots):with(plottools):

R[V] := 0.72*AU: #`starting radius for venus`

AU := 1: #`astronomical unit`

G := 6.674*10^(-11): #`gravitational constant`

m[S] := (333*10^3)*m[E]: #`mass of the sun`

m[V] := 0.815*m[E]: #`mass of venus`

m[E] := 1: #`mass of the earth`

x[V] := t -> r[V](t)*cos(theta[V](t)): #`x-coordinate`

y[V] := t -> r[V](t)*sin(theta[V](t)): #` y-coordinate`

x[VP] := t -> diff(x[V](t), t): #` x-velocity`

y[VP] := t -> diff(y[V](t), t): #`y-velocity`

T[V] := m[V]*simplify(x[VP](t)^2 + y[VP](t)^2)/2: #`kinetic energy of the system`

V[V] := (-G)*m[V]*m[S]*1/r[V](t): #`potential energy of the system`

L[V] := T[V] - V[V]; #`lagrangian of the system`

EL[Vr] := diff(L[V], r[V](t)) - diff(diff(L[V], diff(r[V](t), t)), t) = 0: #` e-l for the r-coordinate`

EL[`Vtheta;`] := diff(L[V], theta[V](t)) - diff(diff(L[V], diff(theta[V](t), t)), t) = 0: #`e-l for the theta-coordinate`

EL[V] := [EL[Vr], EL[`Vtheta;`]]; #` system of equations`

F[V] := G*m[V]*m[S]*1/R[V]^2: #`gravitational force for venus starting position`

omega[V] := sqrt(F[V]*R[V]*1/m[V])*1/R[V]: #`angular velocity for venus starting position`

IC[V] := [r[V](0) = R[V], D(r[V])(0) = 0, theta[V](0) = 0, D(theta[V])(0) = omega[V]]; #`initial conditions, r-position, r-velocity, theta-position, theta-velocity`

SOL := dsolve(EL[V], IC[V], [r[V](t), theta[V](t)], numeric, output = listprocedure); #`numerical solution`

Error, (in dsolve/numeric/type_check) insufficient initial/boundary value information for procedure defined problem
 

I have included both the initial values for r,dr/dt, theta and dtheta/dt.

I'm not sure what other initial conditions I could be missing?
