I am attempting to apply some routine tests to determine the convergence of series with positive terms. I have run into a little difficulty with the root test. I am using surd( ) as shown below, but Maple will not give the exact value, which in my example, should be exp(6). Why is this happening and is there a way to get the root test to work?

Thanks!

How can I successfully input the following problem and be able to solve it. I have been trying with no luck. Please advise. Problem: Find the mass of a planet of radius (R), if its density at each radius (p) is δ= (p+1)/p. Notice the infinite density at its center, but finite mass M=∫∫∫δ dV. Here p is radius not density. Ok, I have the answer but have not been able to get with maple. Answer: Mass=∫∫∫psin(Φ)(p+1)dpdΦdΘ= 4/3∏R^3+2∏R^2....

How can I have Maple construct a time sequence?

My problem states 70 observations, but if you can assist me with 10, Ill figure out hte rest. so pretend there are only 10 observations... 140,159,138,102,84,126,147,126,103,92... Thank you to anyone who can help!

Hi folks, I am solving a boundary value problem numerically using dsolve. I would like to pass the resulting solution (which I gather is really a procedure) back into another differential equation as a coefficient.

M:=x(xi)^2+1:

ode1:=diff(M*diff(x(xi),xi),xi)-0*x(xi)=0:

ics:=x(0)=0,x(1)=1:

sol1:=dsolve({ode1,ics},numeric,output=listprocedure):

y_sol1:=sol1[2]:

y_sol1:=rhs(y_sol1):

% I could then plot the solution using 

Hi Everyone:)

I'm doing a mini project at the moment and I'm pretty stuck with how to go about something on Maple...

My aim is to get the catenoid from an initial cylinder by use of an iterative method.

To find the minimal surface r=g(θ,z) - the catenoid - I want to minimise the Dirichlet integral (in cylindrical polar coordinates)

I'd like to be able to plot a function that not only has a range for the dependent variable(s) but also for any "variable constants" that may be in the expression.

For example, if I wanted to plot the following expression :

                    y = A sin(wx + c)

and also to explore its behaviour over the following ranges for A, w and c :

Hello!

It seems there's some problems with spaces in the name of equation

As you can see the 'SOLVE' command can't substitute variable 'b' in my example, if 'b' variable wasn't defined BEFORE the equation with spaces in its name....

assume i have a number 26 and assume a prime number not greater than a value, let it be 5

then it is like a division and factor into 5^2 + 1

if prime number set to 17, then it will output 17 + 3^2, 

the output will be in terms of prime number, such as  a^3+b^2 + c  where a and b are prime number

it should start from greatest prime number given as a parameter in function

Good morning,

my name is Agnieszka Dymek, I'm a Polish student and I have a question or request. I'm looking for a quite difficult, interesting problems to solve it on Maple. I need this for presentation on lecture, for my friends - it have to be exercies with application different, special function of Maple programme. I was looking for it on Polish websites and I didn't find anything interesting and complicated. 

If You have something in database or somewhere,...

I tried to use the parallelized Map function in Maple 16.

The following code worked as expected:

with(Threads);
Map(`^`,[1,2],2);

But then I tried:
Map(`op`,[[a,b]]);

and the Maple kernel crashed. This happens every time.

Any ideas what can be a reason of this?

my code is almost done but in the end my matrix command is not getting values from array command due to which am not able to get my solution and graph. Am attaching worksheet please let me know how to recorrect it. Thanks

Hello,

I got problem with assuming and solve.

`assuming`([solve(abs(-2*r*(-1/2)*(1+sqrt(1+4*r))/r)<1)],[r>-1/4]);

There is nothing happens... Neither solution or some errors

What am I doing wrong?

Hello! Firt time in this amazing website, from which I have gotten may useful responses in the past!

Please excuse any "misbehavior". Any suggestions will be greatly appreciated.

My question is about theu use of arrays. Specifically, I want to beable to collect matrices in an array. With collect I mean to do something like this:

I want to sovle two equations given as a function
G1 and G2
G1 is defined as
function y = G1(x)
y = (2*x*log(2*x)+(1-x)*log(1-x))+(.0009*x*(1-x));
G2 is Defined as

function y = G2(x)
y = x*log(x)+(1-x)*log(1-x);


when I solve the wquations using code
syms x1;
syms x2;
ans=solve(((G1(x2))-(G2(x1))/(x2-x1))-diff((G1(x1)),x1),((G1(x2))-(G2(x1))/(x2-x1))-diff((G2(x2)),x2),X1,X2);
following error occur


??? Error using ==> sym.solve at 73
