Nm= p1. p2 + 1, for m more than or equals 1.


So N1 = p1 + 1 = 2 + 1 = 3, N2 = p1 p2 + 1 = 2  3 + 1 = 7, etc.


We prove that Nm is not divisible by any of p1, p2, . . . , pm, so that Nm is either a prime or it is divisible by a prime larger than pm.


(c) Use Maple to find out which of these numbers Nm, for m = 1, 2, . . . , 15, is actually prime.


Use Maple to compare pm with the smallest prime number that divides Nm, for m =1, 2, . . . , 15.


Extremely annoying problem...

I`ve written this program:

It determines the power of the Ithfactor, only one problem. When I try to compute the factor of 512 I get 2_2 (subscript) which is extremly stupid. I want to know how I can change my program so that it can give the power of every ith factor. Thanks!


I`m using this program to find the largest prime factor:

Problem: If I insert largest_prime(p^n), where p is prime, it returns n. Which I dont want! I want p to be returned.

Please help me!


Solve equation ...

Why can't maple 15 solve this eqn. [n= 10]



What is the command to get a sequence of the first twenty prime numbers

Find the product of the square root of all prime numbers less than 100.
Hint: The function isprime determines the primality of an integer.

I've been given a question:

Let pn denote the nth prime number. Then p1 = 2, p2 = 3, p3 = 5, p4 = 7, p5 = 11, . . . .

It is known that the infinite sum 1/p1 + 1/p2 + 1/p3 + · · · + 1/pn + · · · = infinity.

Find the smallest positive integer N so that 1/p1 + 1/p2 +1/p3 + · · · + 1/pN−1 + 1/pN > e. [Hint : ithprime(n) generates the nth prime number.]

How do I start off?

Many thanks!

I dont know what to do any further...

I have some function containing HeunG as a function

it is of the following form

f(k)=argument(functions containing HeunG) - ln(2)*k

now plotting this works...

But when differentiating with respect to k and then plotting it gives me the following message:

Warning, expecting only range variable k in expression (I*((1/2)^(1/2*I*k))^2*HeunG(3,-9/2+3/4*I*k-3/4*k^2,-1+1/2*I*k,-1/2+1/2*I*k,1/2,1+I*k,1/2...


I have enjoyed Maple computer algebra system as a platform for some work on prime constellations.  A summary of my work is here -

At the bottom of the page are 3 relevant files and the filenames start with "A constellation"  Two of those files are .mw files.  The code searches the integers for solutions, and it works fine, but after about half a day, it consistantly crashes.  I...

Hi. Can anyone help me with getting all the prime numbers from 1 to 2000 in maple with "from 1 by 1 to 2000 do" and maybe use "if"? How do i make this?

I'd like to take the output of ifactor(n::posint), the prime factorization of n, and index the terms of the product to a list. ie: ifactor(256)=2^8 so [2,2,2,2,2,2,2,2]. or 135 -> (3^3)(5)->[3,3,3,5].
Any suggestions? 

How do I uninstall everything associated with Maple Prime?  I don't know how I got it and don't want it!  I don't know what it does and don't need it.  Operating with new iMac running OS 10.7.4.  It's 3:36 AM and I've been trying to eliminate it fot the last several hours!!  Help now please before I go nuts!!

Hi, does anyone know how I go about getting the y''(x) derivative notation to render properly in Maple TA without the primes being unreadably small? Ideally I'd like to author the question in LaTeX.


Many thanks in advance.

I am working over F_p, where p is prime. When p = 2, the number of 2x2x2 arrays (aka hypermatrices or tensors) over this field is 2^(2*2*2) = 256. Of those 256 arrays, I only want the symmetric ones: that is, if x_{ijk} is the ijk-th element of the array X, then x_{ijk} = x_{ikj} = x_{jik} = x_{jki} = x_{kij} = x_{kji}. Is there a quick loop that does this?
