## Mixed Fraction Question...

Hello! Im kinda new to maple so it must be a noob question :) im using it for like 24 hours to get around some basing math in it :)

Just got some understanding of this 2d/1d/worksheet/document modes and stucked at some operations with fractions.

1) How do i enter Mixed fractions to calculate right?

2) How to compare Two or More fractions?

3) How to get output in mixed fractions? or to expand fractions.

## Generating Samples from Custom Probability Distrib...

by: Maple 14

Maple's Statistics package contains many predefined probability distributions; well-known ones such as the normal distribution and lesser-known ones such as the Gumbel distribution. For these distributions, we ship efficient algorithms that can quickly generate a large number of sample points. To generate a sample of size 106 of both of these distributions, and print the time it took to do this (in seconds), you can run the following:

`with(Statistics):`

## Problem with a taylor/series expression...

Hello all,

I have a little problem with an expression I have to develop in taylor/series.

Here it is:

I want to develop it in "nu", giving that "nu" is a small parameter, and it says that it doesn't exist a series expansion.

But when I can obtain the series expansion of the "sqrt" part only of the expression, which yields:

## Computing Digits of the MRB Constant

Maple

The MRB constant is defined at http://mathworld.wolfram.com/MRBConstant.html.

On about Dec 31, 1998 I computed 1 digit of the MRB constant with my TI-92's, by adding 1-sqrt(2)+3^(1/3)-4^(1/4) as far as I could. That first digit by the way is just 0.

On Jan 11, 1999 I computed 3 digits of the MRB constant with the Inverse Symbolic Calculator.

## How to write this in Maple notation?...

I want to compute expected utilities, i.e. I have a random variable and a utility function, e.g.

with(Statistics);

X:=RandomVariable(Normal(mu,sigma));

u:=t->1-exp(-phi*t);

and now I want to compute the expected utility, i.e.:

## Plane lines and volume...

Hello,

I have Tetrahedron and I know all it's points I need to compute it's volume.

I have computed the square of the triangle and all I need is the hight.

Thanks a lot.

## Find cutting points between plane and y=ax+b...

Hello,

I have a plane x+2*y+3*z = 0 and a point A(1,2,3).

From A there are 3 lines :

P := (1, 2, 3) P1 := (-1, -1, 0) L1 := P+t*(P1-P)

How to find the cutting points between L1 and the above plane?

How to find a cutting points between planes? 2 3 4 planes etc.

## finding out the factor of a large number...

do u have any manual procedure , may be in vedic mathematics, to check out if  large number like 600851475143 is a prime???? also to find out the posssible factors for that number....

## math display test

`2-4*x*BesselI(1,x)-x^2*BesselK(2,x)`

The too short 2D math area width is still a problem (I have requested the solution of this problem many times along the beta period)

Edit: timing of posts is still an issue (it was also an issue during beta...

## MRB Constant K

Since the MRB constant is an alternating sum of positive integers to their own roots, f(n)=(-1)^n* n^(1/n); a thorough understanding of the changes in f, as n changes, is important.
In this blog we will begin to explore the derivative of f at integer values of n, and as n-> infinity. I am not sure weather this will help us in computing more digits of the MRB constant since we already know so many,

## Converting a text line to math...

There must be an easy way to convert a line into math?

Sometimes you've gone to all the trouble to type out a lengthy line of math to operate only to find out it's in text mode.

Is there a way to change it over to math?  I've tried highlighting and F5 but that didn't work.  Are we stuck to having to retype the line(s) over again?

## How can I get all root of polar equation??...

Hello

when I solve the equation about "     cos(2*theta)=1/2       "   by   " solve(cos(2*theta)=1/2,theta);"

I just get the answer "Pi/6" only

but I want the all root within "0 to 2*Pi"

How can I get the all root by limitting area of root??

On 4th May I submitted Ploting 10 functions to plot mentioning codes with with Mapple.
