M takes the lead again. At the wolfram demonstration page there are thousands of apps. From games to astronomy.

Hi;

Do you have an idea of how I could learn Maxima?

You should take some math problems and do them in Maxima.

Learning Maxima's functions isn't the hard part, there are always the man pages. The hard part is using them correctly, which is true for any CAS.

I agree, start learning now how to use your computer to help with your math.

I recommend Bafflers, Series, What do you think and Is this cool with you threads to begin with. That should keep your hands full for a while.

I heartily recommend the problems in computer math especially the ones solved by geogebra!

But I am a complete Novice in this field, even if I pick a problem I won't understand how to do it with Maxima

Everybody starts as a complete novice, most stay there. Some do graduate to the position of student.

You do not have to force it. Start slowly and on problems you have done already. First you must convince yourself that it really works.

Learning Maxima's functions isn't the hard part, there are always the man pages. The hard part is using them correctly, which is true for any CAS.

That is true but in order to start learning it correctly, I need to have a tutorial on how to make the language work(in some way, not necessarily the optimal).

Maxima has limited documentation and no forums that I know of. You will have to experiment.

I do not have any how to maxima book. I do not know of one.

Stefy already knows the amount of Maxima I need to know to start working. He could shed light

Yes he could but a CAS is not a spectator sport. It is not a bunch of lectures given by a professor. It is a hands on thing. You have to get your hands dirty then we can help.

I am now going to cook some chicken cacciatore, Angela style. see you afterwards. Have a good day at school, study hard.

I know but not unless I understand its syntax and how it is programmed, I will need some lectures. For example, I do not understand the loops, string processing, type conversation, etc in Maxima

I will go over them with you but remember you will be using it as a CAS and will have little need for those procedural goodies.

The thing I hate about Maxima, now that I've used M for a while, is that it doesn't have a few functions ehich are a must, such as Select, Total, etc.

You can program them and include them in the maxima initialisation file.

Suppose I am asked **Find the number of 4 digit palindromes that are divisible by 7**, then I'll need string processing

Hi;

Yes, that will call for using your CAS as a language.

and those problems appear in Brilliant

Your problem #22, has or will eventually.

I am writing up the solution.
