How can I tell to Maple that the sum: Sum(v(n)*S(n),n=1..N) where S(n+1) = S(n) + xi(n+1) can be rewritten as: Sum(x(n)*xi(n),n=1..N) where x(n)=Sum(v(k),k=n..N) ? thanks

hi, would appreciate some help in checking limit series in Maple using d'Alembert's test for convergence (if it's possible). the only limits I can get in Maple is either ∞ or 0 (and I need to be more specific). thanx a lot!

I attempt to draw a 3d plot using plot3d.  The function contains a weighted combination of absolute values.  To simplify the problem statement, suppose drawing -abs(x-y) for x=-1..1, y=-1..1.  It was found that near the zero plane, the plot become sawtooth like, which is an unexpected result.  How can I remove this effect?

How does one do the indeterminate vector product with and Dyadic calculus operations with Maple 12?

I just upgraded to Maple 12 because of its ability to perform abstract index calculations. However, I'm having trouble getting started with it. My first problem is with the Simplify command: if I define a completely symmetric tensor using the command

Define(T,symmetric);

and an antisymmetric tensor using the command

Define(w,antisymmetric);

then

Simplify(T[mu,nu,rho]*w[mu,nu]);

correctly returns 0. However, if I define T to be symmetric in only its first two indices,

Define(T[mu,nu,rho],symmetric={mu,nu});

Hi all,

I just found Advisor by Robert Israel.  I followed the instructions, but it won't work

Here's what I did.

I unzipped the 3 files (maple.hdb, maple.ind and maple.lib) in the zipped folder to an advisor named directory in the Maple folder

I created Maple.ini and put   libname:= `c:/Program Files/Maple 11/Tools/Advisor`, libname:   as the sole line in the file as it says.  I put the Maple.ini in the main Maple 11 folder and also tried it in it's bin.win folder.  No luck.

I have the expression

p(x,a) w''(x) + q(x,a) w'(x) + r(x,a) w(x)

How could I obtain p(x,a), etc.?

Thanks,

How do i approach this problem?

Hi, I'm rather new to Maple but I have to find a composite number n which has the property that all her coprimes a fulfill the expression "a^(n-1) - 1 mod n = 0". I already found out that such numbers are called Carmichael numbers. But of course I need to use Maple and the information I was given by our professor. My problem is that I have no idea how to check if "a^(n-1) - 1 mod n = 0" is true for all coprimes of a given n. How do I? ;) btw. I don't know if I used the correct vocabulary here, so please forgive me if I expressed something wrong.

I have this problem

I have to solve something like this

for i to 17 do

solucion[i] := solve({item3[i], item4[i]}, {x, y})

end do

and I obtain in the answer for example

solucion[1] =             {x=2,y=3}

solucion[2] =             {x=3,y=4}

and I would like to create a vector containing all the values for x and all the values for y like x[1]=2  x[2]=3 and so on

 

The position of a particle in space at any time t>=0 (in seconds) is given by x(t)=t^(3/2), y(t)=2t^(5/2), z(t)=t^2 (in meters). Use the connamds diff and fsolve to find the time t when the particle fisrt reach the speed of 300 m/s.

thank you!

If I have an expression which represents the following:

Not sure how to compute my question into maples. Tried various ways and nothing has worked yet. Need help, I am new with Maples. Here is the problem that I am trying to enter into maples:

 

find arc length of space curve:

r(t)= 2e i + ecos(t) j + esin(t) k, where t is > or = 0 and < or = to ln(3). r(t), i, j, and k all have vector arrows above them.

Can anyone give me a hint on how to enter this into maple?

 

Dear all,

Im solving the following equation: V=I(t) * Z (V)

I substitute I and Z with the corresponding equations and I solve for V :

V:=solve(V=(1.027*exp(-t/0.282)+0.051*exp(1/t+(1.766*10^90))))*(2.433*10^3*exp(-0.008*V)+780),V):

and maple solves nicely  it using LambertW and i can plot V for a range of t.

I want to do the same but instead of the equations of I=f(t) and Z=f(V) to use straight the values from tables like:
