MaplePrimes Questions

I'm quite confused by this matter. The following equation (for example) is written into Maple 12: y=e^0.05x Then it is highlighted, right clicked -> copy. Pasting into for example notepad gives: y = exp(0.5e-1*x) This is not the original equation. 0.5e-1*x is not equal to 0.05x?? Any help greatly appreciated.

Hello there...

My name's Gilberto and i'm tryin' to make something out of one particular PDE...

Let me span it for you quick:

I'm trying to discover the solution of Cauchy's heat equation for the cirlce S1 = {x mod 2p}, given the following parameters:

ut = uxx, u(0,x) = phi(x), t > 0, x belongs to R

I'm currently thinking that my next step is solving that equation using the Poisson integral. Is that correct?

solve(exp(-x)-x = 0)

gives 'LambertW(1)' intead of '0.56' which i found by simple fixed pt iteration.

I have this commands:

> for i from 1 to 10 do x1:=1*i:  g:= x1*exp (T) -1 : T=fsolve( g,T) : y1=3*T end do;               

If i execute if i=1 the first lines will be:

x1 := 1

g := exp(T) - 1                  

T = 0.

y1 = 3 T

Now my questions are two:

 

how to covert function to expression???

hi all....how to find pseudo inverse in maple...like the one 'pinv' in matlab.

is there any command to generate identity matrix,zero matrix

thanks

How do I define a distribution with an arbitrary mass function so it can be used exactly like those predifined, e.g., Statistics:-Mean(Poisson(lambda), Statistics:-MGF(Poisson(lambda),t), etc? As an example, Rademacher distribution can be used, or its straighforward generalization with probability of +1 being equal to p and that of -1 equal to 1-p=q. Thanks.

Hi there,

I am wondering if it is possible to create custom feedback based on results of tests or exercises?  For example, if a user receives 50-60% I would want them referred to a specifc URL or set of static web pages providing more detailed informtion on the given topic, however, if they receive , say, 61 - 70% they could be referred to yet a different URL, web site, etc. 

 

thanks,

Jeff

hi all...i want to write a procedure just to execute a set of maple commands without any input args e.g do some calc and plot series of graphs..i am facing 2 problems

1.inside procedure all lines are not  displayd only last line of command inside the proc is diplayed after execution

2.im choosing a proc to exec a series of commands because i can use the debugger to debug the set of codes else i cannot.

I would like to change the way arrows looking Maple under fieldplot3d. Particularly I would like them to have a rounded head and a simple stick for the base of the arrow. Anyone know how to do this? I have seen it done before, just not sure how to implement the code to do it. Thanks in advance!

I was curious if anyone has every seen an english translation of Jordan's Cours d' Analyse. I've read many author comments praising his work and was interested in trying to find a copy in english. Anyone care to comment?
