How does Maple  reduce that to unity? Thanks.

S := `assuming`([simplify(-sin(Pi*(alpha+n+beta))*sin(Pi*beta)/(sin(Pi*(alpha+beta))*sin(Pi*(-1+n+beta))), trig)], [`and`(`and`(alpha::real > 0, beta::real > 0), n::posint)])

I have to plot a graph where an equation C is dependent to two variables, and the equation changes depending on value of d.

I know plot3d(equation, range, range) gives you graph, but is there a way to plot a graph in only places where data sets are given instead of one smooth graph?

 

 

Below is something I tried to do which is not giving me results i want.

 

Hello,

I was trying to solve this nonlinear ODE using dsolve:

ode:=(diff(f,x)*diff(g,y)=1): dsolve(ode);

but got: Error, (in ODEtools/info) R equired a specification of the indeterminate function

 

I'm not sure what Maple means by "indeterminate function" .. does that mean I need an explicit function for g(y)??

I would assume that Maple would be able to do this without knowing g(y) since one solution is (1/n)*f(x) + n*g(y).

Thank you.

I have a 6*6 matrix which is A:[1,1,1,1,1,1],[1,0,-1,1,0,-1],[2,1,0,2,1,0],[4,1,2,0,4,1],[1,-2,1,-6,0,1],[5,4,-1,-2,5,0]

How can I show the system Ax=b is consistent or inconsistent if

x= [x1          b= [1

     x2                 0 

     x3                 1

Hi i was wondering if anyone could tell me what code i have to program the Bisection Method. I can't seem to get the while loop to work. it only gives me the first iteration and stops. Here is what i have done
 

 

f:=x ->x^3-x-8:
a:=2;
b:=3;
f(a);
f(b);

while sign(f(b)) <> sign(f(c)) do
if (f(b)*f(c)) > 0 then
b:=c:
else
a:=c;
c:=(a + b)/2
end if:
end do;
print(c);
2.5
 

I just can't get it to work.
 

I use Maple 9.5 on a Mac PowerPC G4.

Recently I have been unable to open a new worksheet. I have restarted my machine numerous times.

Do you have any suggestions for what to do--I am away from home and don't have the software to reload.

I think the problem first started because I opened some old files--running Maple 4 or 5.

 

Thanks,

Roger

 

Hello,everyone,

I have a problem with the symbolic equations,

would somebody help me to solve the follow equations, thank you very much!

This is a follow-up to an earlier post about CovarianceMatrix.

There are several ways in which Statistics:-CorrelationMatrix can be improved.

CorrelationMatrix shares some inefficiencies with CovarianceMatrix, by computing correlations between the n columns, pairwise. But in doing so it also computes...

Hi everybody,

 

I am doing the following:

If you could go to CH6 then Section 1 then Exercises. #30 is giving me trouble

:( plz&thx

It seems Maple's Sample command cannot handle self-defined distribution well. Check this:

I am in a college level physiology class, and have been assigned the task of deriving the Boltzman equation with Maple.  I have never used Maple before and find myself at a loss how to even start.  I've read through the tutorials and still am having difficulty using this program.  To define Boltzman equation, we are supposed to plot the Boltzman curve of force vs probability that channel is open.  Force is just equal to x, and probability that channel is open would be on the y axis and is defined as a/(a+b).  The second component of the equation involves t

given 4 points ex. (-3,4),(-1,3),(0,5),(1,6). how can I find two polynomial of degree5 passing throuh these 4 point. Is is also possible to fing more than two ? How do you know ?(what if you want to find polynomial of degree three thru these4 point, how you know how many there exist?) I just made up those point...

To enable page numbering, I am instructed to select Page Numbers fom the Format menu, however, there's no Page Number choice on the Format menu of my Maple 12 installation. What can I do?

Thanks, Paul
