## How to Lock Links of a Robot ?...

ABB_IRB_120_Model_IK_OK_6_RealParamsLinearization.msim

I did the model of the ABB IRB 120 in MapleSim, but I would like to lock several links but I do not know how to do it.

Also I need the differential equations of the robot, which must be six differential equations but in MapleSim equation extraction page there are lots of equations.

Please can you help me ?

## How to produce animation in Threads?...

In the worksheet below I produce a sequence of frames for an animation by distributing the task into several threads.  The result has strange artifacts as we see in the sample.  The artifacts vary randomly from run to run.  Am I doing something wrong?

 > restart;
 > kernelopts(version);

 > kernelopts(numcpus);

Draw a simple picture:

 > frame := proc(t)   plot(x^2 + t, x=-1..1, title=typeset("t = %1", t)); end proc:

Generate a sequence of pictures:

 > frames := Threads:-Seq(frame(t), t=0..1, 0.05):

Animate the sequence:

 > plots:-display([frames], insequence);

## How to calculate standard error in nonlinear fit p...

Hi all,

I have a data set (see .txt file attached) to be fit to the model function A*sin(B*x+C)+D. Calculating the parameters A, B, C, and D is easy enough, but is there a way to have Maple return their standard errors?

## Monospaced font problem...

Hello,
I am new to Maple and have some problems with fonts in Maple's forms. How can I increase the size of the monospaced font? (see the screenshot).

How would I go about getting true or false returned on these propositions?
I have tried just about every eval and various syntax methods, but nothing has worked so far.

I know most can easilly be done by hand/thinking, but I'm sure Maple should have a way to do this as well.

∀n∈Z:2n>n+2   ,   ∃n∈Z:2|(3n+1)    ,   ∃k∈Z:∀n∈Z:n=kn   ,   ∃k∈Z:∀n∈Z:2|(n+k)   ,   ∀n∈Z:∀k∈Z:(n>k∨k≥n)

## How to find coordinates of the projection of a poi...

I am trying to find coodinates projection H(x,y, z)  of the point P :=<x3, y3, z3> on the line AB, where A:= <x1,y1,z1>, B:= <x2,y2,z2>. I tried

```restart:
with(LinearAlgebra);
A:= <x1,y1,z1>:
B:= <x2,y2,z2>:
P :=<x3, y3, z3>:
H:=<x,y,z>;
solve([DotProduct(B-A, H-P, conjugate = false) = 0, B-A = k*(H-A)], [x, y, z, k]);```

I can not get the result. How can I get the coordinates of the point H?

## Simplifying a quotient of multivariate polynomials...

I have a hard to understand quotient of multivariate polynomials- my intuition is that the denominator nearly divides the numerator - and it could be rewritten as:

remainder+(much simpler numerator)/denominator

as far as I can see the functions quo and rem aren't designed for this - but I'm certain that people in the maple community must have overcome this kind of problem before

## How to force Maple to approximate a radical into a...

For example...

Using a \$2 calculator I get that rad(2470) it is approximately 49.699094.

I haven't used Maple in several months and was surprised to see that I couldn't easily search the answer to this question. Something like eval() does not work on this.

## Why the time difference varies for the same calcul...

There is a time difference variation between two clocks (0.124, 0.120) and between the same clocks for the same calculations at different times(0.07, 0.124 and 0.120, 68. What is the reason?

## How do I find the run time of my program...

There  are commands tic and toc in matlab program.

tic

toc

toc - tic

This gives the run time for the program.

Even in excel, we can find the difference between clock times at the start and end using NOW commands.

Is there a similar way to use maple commands to find the running time of a program.

I want to find the time taken by the student to solve the quiz questions in the enclosed doc.
