Let . Find ?

Hi,

How would I ask Maple to display a expression and then evaluate it?

For example

Diff(5,x)=value(Diff(5,x));

or

Diff(5,x)=diff(5,x);

But do I really have to copy the lhs to do rhs every time?

Any simpler way?

PS: I am using 1-D input and I'd like to keep it that way.

Hi.
I am trying to use a new Physics:-Library:-SortProducts command. However it doesn't work in my case.

restart; 
with(Physics); 
with(Library); 
Setup(mathematicalnotation = true); 
Physics:-Setup(anticommutativeprefix = psi); 

for i to 4 do 
ap[i] := Creation(psi, i, notation = explicit); 
am[i] := Annihilation(psi, i, notation = explicit) 
end do; 

z := A*ap[2].am[2].ap[1].am[1]+B*ap[1].am[1].ap[2].am[2]+C*ap[3].am[3].ap[4].am[4]:

Solve the following system of equations

The solution to the following differential equations results in empty brackets [] and I want to know their content

> Restart; ode := B*(x-1)^2*(diff(y(x), x, x))+C*(x-1)*(diff(y(x), x))+(A-x/(x-1))*y(x) = 0;


> dsolve(ode);

y(x) = _C1*(x-1)^((1/2)*(-C+B-I*sqrt(-B^2+(2*C+4*A-4)*B-C^2))/B)*hypergeom([], [(B+I*sqrt(-B^2+(2*C+4*A-4)*B-C^2))/B], 1/(B*(x-1)))+_C2*(x-1)^((1/2)*(-C+B+I*sqrt(-B^2+(2*C+4*A-4)*B-C^2))/B)*hypergeom([], [(B-I*sqrt(-B^2+(2*C+4*A-4)*B-C^2))/B], 1/(B*(x-1)))

HERE IS A FUNCTION THAT I WANT TO DIFFERENTIATE

I've been wondering if this is possible and i'd be very happy if it is. Is there a way i can format the output of and fsolve(). in such a way that it does not come in curly braces, preferably, it comes out in a colomn-vector form and without the names of the variables solved for. Just the values. 

Secondly, I've been trying to apply the newtons method for my friend here in school but i've been getting an error message...

Let X be the random variable uniformly distributed in the disk centered at the origin O(0,0) with radius 1 and let Y be the random variable uniformly distributed in the square having its vertices A(6,-1), B(9,-2), C(8,-5), and E(5,-4). What is the PDF of the distance between X and Y? Is it possible to find that with Maple? The similar question in three dimensions, replacing a square by a cube and a disk by a solid sphere.

why doesn't this evaluate to a numerical value when u supply an a value for 'a'.

can someone modify it......

I've plotted the solution to a GLM using the plot3d function, but a portion of the plot is irrelevant to the presentation of the results. I can define the portion of the plot I want to discard based on the x and y coordinates, but I've gotten errors for every if-then statement I've tried to include. Any suggestions on how to properly integrate an if-then statement into the syntax?

Aslam-u-Alikum... How are you? Hope you will be fine. I want to determine the eigenvalues of differential equation in Maple kindly help me... Problem.docx

A number n is called a double if its base-7 digits form the base-10 number 2n. For example, 51 is 102 in base 7. What is the largest double?
