These are the steps that I need to do

determine the domain and range of the functioon

determine the intercepts and asymptotes of the graph

locate the x-values where f'(x) and f''(x) are zero or undefined

then i need to determine where the relative extrema and the points of inflection occur (this i should be able to do if I can get the graph)

i have to know how to do this for two kind of function for a test tomorrow I missed all week because i was sick and we are allowed to use the software on the test.

here are the functions

Hello,

I have a system which is below:

 

X6-n4-n2, -n3+n1, -n4*X17t+n2*X9t, n3*X17t^2-n4*X17tt-n1*X9t^2+n2*X9tt, 130*X9tt-60*X17tt*n2*n4+60*X17tt*n1*n3-40*n2*X11+981*n2+60*n2*n3*X17t^2+60*n1*n4*X17t^2, -1500*X9tt*n2*n4+1500*X9tt*n1*n3+2250*X17tt+1000*n4*X11-14715*n4+1500*n4*X9t^2*n1+1500*n3*X9t^2*n2, n1^2+n2^2-1, n3^2+n4^2-1

I need to do primedecomposition for it. Maple could not do this for me kernel was lost. However system is not very big.

With version 10, I did this:

gammadist:=(x^(alpha-1)*exp(-x/theta))/(GAMMA(alpha)*theta^alpha);

simplify(int(gammadist,x=0..infinity),symbolic);

The result of the integral is 1.

When I do this exact same thing in version 12, I get an integral without any symbolic computation.

If I use assum(alpha>0): additionally(theta>0): then it will give me the same result.  However, in version 10 I also did

mgf:=simplify(int(exp(t*x)*gammadist,x=0..infinity),symbolic);

Hi, I'm working on the Smoluchowski equation (essentially the diffusion eqn with an extra derivative) diff(u(x,t),t)=k*diff(u(x,t),x)+D*diff(u(x,t),x,x) k is piecewise so the function has to be solved numerically, the boundary values are specified u(0,t)=u(1,t)=0 but i need the derivative at the boundaries D[1](0,t) and D[1](1,t). It seems to be simple to evaluate a numeric derivative of an ODE but I can't see how to do it for a PDE. Any help welcome, even some sort of brute force method if necessary. Thanks, Ryan

 

Hi,

I tried to find the limit of the following equation using l'hopital's rule, when sigma approches to zero find i couldn't find it.

Now i want to use Taylor series to find the limit of the following equation, when sigma approches zero.

Hello everyone

I have a cost function I would like to minimize. It is a fairly simple function that only contains multiplications and additions.

Only problem is, this function has about a hundred variables, but they can only be between the interval [0,1] so I guess it makes the problem easier.

Is it possible to write a little program in maple that can be ran as much as I want it to run and that could try to find an approximation of the actual solution? (By trying random numbers between 0 and 1)

Thank you very much

Can Maple embed ActiveX objects ?

Hello, I've already posted a similar Problem, but didn't get any answers. Now I think I got the solution, but now there pops up another problem.

I try to run the openMaple sample java code from the samples folder in Maple. I'm running Windows 7 with Maple 13.

When I run test.java, a Popup appears with:

"Error launching OpenMaple splash screen"

with an OK button.

After this, a Popup appears with

"Fatal Error, unable to open C:\Program Files\ Maple 13\bin.win\libgmp-3.dll. This library is required for Maple to run."

Hi, MY problem below is basically like this: I have a grid and need to plot points on it. The color of points depend on another parameter x. So, if x=

Hi,

i got some problems trying to run the example test.java. I have Maple 13 on a ubuntu machine.

for your info:

$MAPLE=/home/thomas/maple13
$LD_LIBRARY_PATH=/home/thomas/maple13/bin.IBM_INTEL_LINUX


Now the problem:

Compiling the java file works, but when I try

java -classpath "$MAPLE/java/externalcall.jar:$MAPLE/java/jopenmaple.jar:." test

this exception appears:

Error loading libraries: java.lang.UnsatisfiedLinkError: no jopenmaple in java.library.path
 

My goal: given G(z,w), find the polynomial, P(n), in the partial derivatives of G(z,w) over the integer such that 

d^n z/ dw^n = P(n) / Gz^(2n-1)    where Gz= partial derivative of G with respect to z.

Step 1. Differentiate G(z(w),w) w.r.t w n times. Formulae are known for doing that (Mishkov, Tsoy-Wo Ma),

Dear Maple Users

I am trying to minimize a cost function C subject to conditions t1>0 , t2>0 and t1< t2 by using maple 10

It seems a picture inserted or plot command generated is not movable in a document ?

If I shrink the picture,that will be in the center of the page,but this is not good when I should print the document.

can't be dragged to anywhere?

 

What keyboard configuration must have the Win XP to use the keyboard shortcut "Shortcut Keys" and not the key combination "International" to introduce 2-D math expressions. I refer to the help "2-D Math Shortcut Keys and Hints".
The configuration I have enabled is:
Input Device Language: Spanish.
Keyboard layout / IME: United States International.
Gracias

Hi, I am wandering whether are some functions to compute all irreducible polynomial and prmitive polynomial over Galois field. For example, I want to all the irreducible and prmitive polynomials of GF(2^5). are there such commands to perform that? thanks
