@ Mac,

You've make your point about plots package. However while the way you defined the function is more proper than the way I did, defining the function as f(t):=.... works as well. All you need is to specify in the box dialog that it's a function.

Hi Acer,

Yes, I wanted to checks its sign visually, by inspection as you said. I tried the command sign(SC3) which gives 1 but that doesn't mean any thing. I have many parameters which are positives. I don't know how to do it otherwise.

If I know that parameters alpha_6,, mu_1,... are positives, is there a way to check the sign directly by programmaning without displaing the term?

Any suggestion would be helpful...

Thank you very much Alejandro. The output of lprint(SC3) is easier to convert it in latex manually. I copy and pasted in latex file and then remplace each  alpha[6] by \alfa_6 to the hole file and the same with other parameters. This problem is solved.

Thanks again for being patient with my english :-)

Thank you,

I have maple 15 and mac os X and I've heart that the classical GUI is no longer avalaible on mac. I'm surprised that maple prefers to display "uglier" and longer form rather than the prettier :-).

I have another question: Is that possible to transfert the contents of the 2D form of SC3: in, let's say latex, without displaying it in maple?

Thank you a lot;

Thank you very much for this solution. I am releived with this. However, is there any solution to change the fonte of the GUI? Because this fonte gives like:

alpha[6]^4*gamma[1]^3*gamma[2]^2*gamma[3]+alpha[6]^4*gamma[1]^3*gamma[2]^2*gamma[4]

Given that it is a very large expression, this fonte makes difficult to check the sign of the expression SC3. And How to use the CLI?

Thanks again,
