I was given the following MGF and need some help determining the E(X), Var(X) and P(4.1<X<4.7) using Maple

MGF of X is M(t) = 1/(1-3t) , t<1/3

How can I get Maple to do this for me?

Thanks again :)

Is there a possibility translate Maple code to Reduce code ?

Hello,

do 3D-OpenGL-Graphics in Maple 16/17 on Linux-x86_64 (openSUSE 12.2/12.3)  work with Intel HD 3000/4000 Graphics?

Thank you very much.

Maple 16 is crashing when saving. I have this problem in both

my desktop and laptop (PC, Win7), classic and standard worksheets.

I noticed that short files present no problem, but whenever the

worsheets are, say, more than 5 screens length, Maple 16

crashes when saving.

Anyone with the same problem? Any solutions? Thanks

Hi!

I need to assign a name to a result calculated from a system of equations. In this case, i've got 2 equations and 2 solutions. I want to assign a name to the each of the solutions.

solve({-a+4*b = 0, 2*a+7*b = 2}, {a, b})

{a = 8/15, b = 2/15}

How do i assign a name for a and another for b?

I mean not open these files, and ctrl+A select whole file and copy to one file.

THis is what I have so far.. is there anyone who can help me with this?

Let f(x) = 1/9*x^2, o<x<c

Find c so that f(x) is the pdf of a random variable X.

I have come up with this and was wondering if I could get some help. I cant get it to paste in, but I have

uploaded the file.. Please assist if you can.

How does one solve integral equations in Maple?

Is there any way to convert the output of ToInert to a graph/tree representation?
ToInert's output type is a function and I've tried converting it to an expression  first but didn’t succeed. I've also looked for functions in the GraphTheory package that could help in this process but didn’t manage to find anything useful.
Thank you.

Attached is my sheet. Please have a look.  my_scrach_Sheet.mw

Have a look at the last command of the sheet.

I am trying to extract integrals from the equaions(eq10_1, for example) using 'op', but it isn't working as expected, is it a bug or I am doing something wrong?

Second question: 

I am not been able to do sorting for all these equations, any suggestions?

I have been trying to find a solution to the following equation for ages! 

Vt:=(a*t)+((1/(2*Pi))*((b*cos(2*Pi*t))-(c*sin(2*Pi*t))-b)-295);

I need to find what t converges to, I have solved the equation using a different method and I know the answer is around 0.787 but I need to find the result using the Newton Raphson method, or another iterative method. I am not allowed to use dsolve. or the Newton command.

Hello, 

I have plotted a function f(e) vs. e (see code and figure). However, the graph looks jagged and nasty. I tried increasing the numpoint value but this doesn't seem to work (even at 50,000!). I'm fairly new to Maple and so I don't know any other commands/ tricks to help myself. 

Does anyone know how I smooth this plot?

Thanks.

Code: 

> f := (1+(73/24)*e^2+(37/96)*e^4)/(1-e^2)^(7/2);

Hi!

In the program below, all solutions are found for the equation S.R=T subject to 

the constraints given by eq1 and eq2. I've tried it for a 

few different choices of T and there's usually 80+ solutions.

I want to try more complicated choices of T (for example,

I want the matrix T to have every entry a distinct prime number). 

But then the program crashes. I assume the equations get complicated

or there...

Sorry if this is a bit vague...

I have a list.  I am applying a loop with a condition.  When the condition is met it stops (of course) but how do I get the condition to continue testing against the rest of the list without incrementing the next loop value?

T := Typesetting[delayDotProduct](sqrt(2/3), Matrix(3, 3, {(1, 1) = cos(omega*t), (1, 2) = cos(omega*t-(2/3)*Pi), (1, 3) = cos(omega*t+(2/3)*Pi), (2, 1) = -sin(omega*t), (2, 2) = -sin(omega*t-(2/3)*Pi), (2, 3) = -sin(omega*t+(2/3)*Pi), (3, 1) = 1/sqrt(2), (3, 2...
