This is the second post in a four-part series that started with this post: Generating...

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 10^{6} of both of these distributions, and print the time it took to do this (in seconds), you can run the following:

with(Statistics):

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:

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.

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.:

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.

Please give me an answer including vectors.

Thanks a lot.

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.

It is urgent, please help me!

I guess this is trivial, i just want Maple to apply the convert-to-product-rule:

i typed in sin(x)+sin(x+Pi/3) and looked for some related command in the context menu, but expand,combine or simplify or else didn't work. What did i miss ?

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....

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...

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,

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?

Hello

Please answer my question about my math lab class.

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.

I got some answers and have managed some additional ones.

Please help with items B, C and D

BR and thanks
