Hi everybody,

I have never done statistics in Maple.  In a simple calculation, I need to calculate the RMS of 55 numbers.  The average of those numbers is 100484.3 and it is given that the RMS is 1.28 counts.  I have the a list of the 55 numbers.  Since I don't need a demonstration, it would help me a lot if you could tell me how to load the data from a *.txt file (one number per line), and use the appropriate commands to obtaine the result that is only given.

For the moment, I only need the steps to proceed with the calculations and how to do it in Maple.

Thank you very much in advance for your help.

Hello everybody,

I want to use the physics package in the context of special relativity.  I am mostly interrested with the Lorenzts transformations, not having to unprotect gamma all the time, the 4-vectors for space, time and momentum in (ct,x,y).  For exemple, to be able to calculate the invariant (ct)^2-(r^2).  A small document (or worksheet) would be very nice of you.

I understande that someone could say that I want to use a gun to kill a fly.  But this is a process that will lead me in using it in general relativity and using tensors in my calculations.  It would be very interresting to have a Student,Physics package.  Don't you think so?

Thank you in advance for your trouble and comprehension.

Hello everybody,

This one is an easy one but I cannot find the answers.  Suppose that I clik on the template for evaluating a function.  But mine have two (or more) variables (f=f(x,y)).  I have the x=a as one placeholder.  But I need to have an another inplut placeholder for y=b.  Can somenone tell me how to do it under Windows and under Linux.

Thank you in advance for your help.

Hi everyone,

At some point in my calculations, I want to do some simple manipulations wiht the use of the «clickable» features in M17.  For the moment, I can see directy how to do it by hand and I do it by copy-paste and use the mous to change it a little bit.  But I just cannot find a simple way to do it by simple click.

You will find in this attach question, the maipulations I want to do.  It is starting from equaiton (7).  Am I at the edge where it is simple by hand than with the features?

Thank you in advance.
