Hi,

I have an inverse kinematics model for a double inverted pendulum. There are multiple solutions for each joint angles due to symmetry and I have to choose the appropriate ones. I thought I can use the previous choices and compare them with the current multiple solutions, so I could choose the ones which are closer to the previous ones. However, since the double inverted pendulum moves in in both region at the equilibrium, this aproach does not work. Could you advise...

I watched a webinar by Dr. Robert J. Lopez, titled "Algebra, Trig, and Precalculus Math – All by Syntax-Free Maple".

In it he says he will give his email at the end if anyone wants the worksheet he is using during the webinar.  

I don't think he ever gave his email and, as a Precalculus teacher, I would really like the worksheet.  Please advise.

Hi maplers

I was wondering if it is possible to change default document template and startup code?

How to construct the decomposition-field of the polynomial x^4 + x + 2 over GF(11,1), where GF(11,1)
is Z[11] = Z mod 11 (see ?GF for more info), in Maple?

I want to make an application like the picture in Maple 16. Cuold you help me how to make it ?

Do you have any applications about physics nn maple 16?

Hi every one,

How can I get bouble Curl of this equation

In the above equation, the first term has the Laplacian, the second one has the gradient and in the term "k" is the unit vector and also u=(u1,u2,u3). sqrt(R) is a constant. 

Is there a way to modify icon size into palette?

>eq1:=n=(k[f1]^3+k[f2]^3)/6/Pi^2;


> eq2:=el*V=h_bar^2/2/m*(k[f2]^2-k[f1]^2);


> eq3:=solve({eq1,eq2},{k[f1],k[f2]});

> eq4:=allvalues(eq3):

Solving this i get a very very massive result. Let me take a branch:

eq5:=subs(eq4[2],k[f1]);

I get

1/h_bar*(-(1/2*n*Pi^2*h_bar^3/el/V/m+1/2*...

What is the next two terms for this pattern...

1, -2, 2, -4, 0, ...

Hi/

the code below wroten by Maple 13. I use h=0.29669 and N:=15 and digit=80 fsolve works perfect! but when I changed N:=16 and another number greater than 15 fsolve didnt return result and return some equation.

whould you help me how to resolve this problem?

sorry i upload this code. to run easilySinc_MBVP_V2-temp.mw

thanks

I am playing around with the PolynomialFit command in maple.
If I want to get a return of 1% then I can simply plug in the return at time t
for v in the expression below. That works for all different returns.

Hello,

(sorry if this appeared elsewhere, but it seems my first try to ask this failed)

I tried to use Maple last night to do some heavy computational work, but it turns out (I let him print time()) that he was only active for about an hour.  He did not do anything when my Macbook Pro was on stand-by.

This morning, when he woke up, he was unwilling to stop!  I pushed the "Interrupt the current operation" button...

What are all the maths that are on this program?

Hi, I have quite a long worksheet. When i press enter one by one, the calculation comes out alright. But when I press the "!!!" sign which means execute entire worksheet, not all the equations run properly, is this a problem in Maple15 or am I using the command wrongly? Please advice. Thanks.
