Hello,

I have this problem. I would like to construct clothoid as a transition curve between two arcs. The length of this curve has to be 30 meters. The start azimuth is 0.3773 (rad) and the start radius is -355.835 m.

How could I do that simply in Maple?

Thank you

Like in the version 7 where that variable didn't exist.

There was a recent exchange I was a part of on Maple classic versus standard, etc. It disappeared from the list of "recent discussions" so I tried to track it by other means. A keyword search did not immediately return a helpful link, so I thought I would click on my profile and look for my recent comments from the lists there. But I could only find a list of "questions," "answers" and "posts". My contribution there was merely a "comment" and I can't seem to find any list about those...

would you please help me? 

I have a big problem in differentiating with maple! 

here is my equation. 

L := (alpha, beta, theta,alpha(t),beta(t),theta(t))

how can I find diff(L, alpha) ? 

L=(1/2)*I[a]*(diff(alpha(t), t))^2+(1/2)*I[b]*(diff(beta(t), t))^2+(1/2)*I[c]*(diff(theta(t), t))^2+(1/2)*m[3]*(b^2*(diff(beta(t), t))^2+(1/4)*C^2*(diff(theta(t), t))^2+b*c*(diff(beta(t), t...

Hi, friends

The physics package was provided a good tool to compute Commutator or anticommutator relations. Here, I met some problems.

Example 1:

      restart: with(Physics):Setup(mathematicanotaion=true):

      Setup (op={p[x],p[y]},p[z]):

      alg:=%commutator(p[z],p[x])=2p[x], %commutator(p[z],p[y])=-2p[y], %commutator(p[x],p[y])= p[z]

Hi

I am attempting to do a least squares regression with two variable (HK and S) generating my curve.  The equations are extremely tempermental and won't allow maple to solve them using normal methods, so I'm resorting to numerical methods to minimize the least squares.

I am attempting to create a dataset that I can search for the minimum of "k" and have it tell me what "i" and "j" values I used to get there.  The code below is the basic idea, the...

Hi there,

I am currently working on an ODE model with a diffusion term and I have to analyse it analytically (if possible) with Maple12.

With the dsolve function I have a solution but based on BesselJ and BesselY functions.

My questions are:

• Do you know if it's possible to have a solution without these functions?
• When I add the IBCs conditions, the system is inconsistent, do you understand why?

Hi,

I am using maple x64 to read/ open some large TIF files.   The files are 57 Mb each and I want to open 16 of them.  Maple looses kernal connection twards the end of the calculations each time.  This is anoying. Is there a way to fix this?

If I take the result form y and defign it as y and delete x them maple will calculate 1 more function set.

document setup;

x=read-image (using the actual maple commant)

y=entropy (x...

Hi All,

Is using the NAG package the right way to go about creating the delaunay triangulation of a set of points in 3 dimensions. My points all lie on a surface in R^3.

Thanks. 

I have looked at the maple help for the ErrorPlot function, but i can't make it work for my plot. 

I have the following procedure:

K := 1.; Xrng := [seq(dt*i, i = 0 .. ntime)];

value := array(1 .. ntime+1);

ave := array(1 .. ntime+1);

for j to ntime+1 do:

discountfactor := exp(-r*j*dt);

Stot := 0.;

Stot1 := 0.;

for i to npath do:

Spath := max(Spot[i][j]-K, 0);

Stot := Stot+Spath;

When entering an expression into Maple that is not in simplest form ( Maple desktop will automatically change it to x+y. I have tried subtracting equivalent expressions, using evalb, using convert, and using simplify, but I cannot get 2*(x+y)/2 to be equivalent to (x+y) using the MapleNet web service.

Any help appreciated.

When I use pdsolve to solve a system of PDEs, and tell it to use HINT='*', does the solution I get ONLY contain those obtainable by separation of variables, or does it use separation of variables as a starting point and deliver the general solution? And how can I tell?

Hi,
I want to call Maplets from Flash, 

1.I have been using TA for some years but we have only recently moved from version 4 to version 6. In versions up to version 5, when a question was edited there was a two stage saving process ie. the question was saved and the question bank was saved. Only after these two saves did assignements containing the question reflect the edits in the question. I have an assignment which depends on a question in TA6 and I have edited saved the question. The assignment does not reflect...
