Hey guys, I'm going to go ahead and post the whole problem along with some of the work that I've done so that it won't look like I'm letting somebody else complete the entire problem. Any help would be appreciated. Here goes:

Tom and Jerry are two snail brothers that need to travel five miles to a lake. Tom travels 1 mile on the first day, 1/2 on the second day, 1/3 on the third day and progresses 1/n miles each day. Jerry travels 2 miles on the first...

Hi, everyboyd I wan to draw a vertical line at theta:=Pi  for any function.

How can i do it.

hi.my program is this=

a:=[[2.5,0.05],[-2.5,1],[0,1],[-1.5,1],[-1,2],[1,2],[1.5,1],[0,1],[2.5,1],[2.5,0.05],[-2.5,0.05]]

plot(a)

r:=plot(a)

b:=[[0,2],[0,1]]

plot(b)

v:=plot(b)

c:=plot([-1+1/2*sin(t),1/2*cos(t),t=0..2Pi],scaling=constrained])

d:=  plot([1+1/2*sin(t),1/2*cos(t),t=0..2Pi],scaling=constrained]) ...

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

Hi everyone.. Now, i learn Maplesim.. I want measures force between 2 frame(a and b). which are connected by prismatic joint.

But a force and moment sensor acts as a weld joint.. so althought i measured force but frame b can't move.

who can solve my problem??

thank very much!!!

PS: i want measure force 2 frame to calculate the friction between them.

Hi,

I would like to apply watson lemma on f(t) = 1/((t+1)*((t/a)-1)), with a a constant, and x tending to infinity.

The problem is that my integral I have to compute is not from 0, but from a....

My integral is : I = int (exp(-x*t)*(t^(λ))*f(t), t=a..∞), with λ>-1, x->∞.

I know that if a=0, and (taylor expansion) f(t) = ∑ b_n*(t^n), n=0..∞, then

I = ∑ b_n*Γ(λ+n+1)/(x^(λ+n+1)), n=0..∞.

Hi,

I'm trying to do get the Inverse of Matrix A, I tried this:

> restart;
> with(LinearAlgebra);
> A := Matrix(4, 4, [[1, 0, 0, 0], [0, 1, 0, 0], [1, l, l^2, l^3], [0, 1, l, l^2]]);
                     Matrix(%id = 83774380)
> B := MatrixInverse(A);
Error, (in LinearAlgebra:-MatrixInverse) singular matrix

 And got an error, could someone help me.

Thanks

I have a matrix m with 9 rows and 4 columns and when I enter the command below I get an error message:

num := product((z-(m[s,1]+I*m[s,2])),s = 1..9);
Error, Matrix index out of range

However, there is no problem if I use brute force:

If I extract the denominator of the following expression

> s:=(1/2/Pi+Q*(1-u^2)/(1+u^2))^2/((1+beta^2*(1/2/Pi+Q*(1-u^2)/(1+u^2))^2)*(1+u^2));

maple expands it automatically

s2:=denom(s);

but the result of solving the expanded denominator

solve(s2=0,u);

is different to the result of solving the non-expanded expression

of the system {x^2+y^2+z^2-2*x-4*y-6*z+13 = 0, 2*x^2+3*y^2+z^2-4*x-12*y+6*z-2 = 0} with Maple?

PS. Mathematica 7 solves it.

Hi,

I'm currently using a gridded search to find a global minimum.  I have 4 parameters which results in a really large search size (100 steps per parameter).  In order to reduce my computation time, I'd like to use a gradient search instead.  Does anyone have any code?

Thanks

Hi.i want to draw the picture which is in this SITE http://www.resurs.az/thumbnail.php?file=Qafqaz_Uni_370925279.jpg&size=article_medium  .Please help me...

 

I want to publish a Maple Program on Web. How I do ?
I want a MapleNET Server to run on a pc for fast.

I am very new to Maple and am trying to teach myself until next semester when I will be taking a course.

I am trying to make a GUI based worksheet to display a plot of a vector valued function (in R^2) and its velocity and acceleration vectors. I wrote code in a worksheet and it seems to work, but I am having trouble getting the plot to work when I put the code in a slider (to update continuosly as the value of t changes with the slider). I understand there are differences...

In the following examples I attempt to remove integer multiples of Pi from sin/cos. Nothing works.

Why? How do I make it work?

Thank you.

term1:=cos(Pi*(3*a-2*n));
> term2:=cos(3*Pi*a+2*Pi*n);
> term3:=cos(3*Pi*a-2*Pi*n);

                     term1 := cos(Pi (3 a - 2 n))
