Programming...

February 17 2009 Jabz 433

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'm an upper-level undergraduate mathematics student, and I'm working on a project to create an algorithm to determine if any function is convex.  My Professor suggested that I post in this forum, to appeal for suggestions.

I hope to apply the algorithm to single or multivariable functions, which have polynomial, power, logarithmic, exponential, trigonometric, or any combination thereof.  The algorithm should work on any predefined domain.

Hi, all, I know there is a polynomial function from GF(2^m) to itself, but whether there is a mapping from GF(2^m) to GF(2^n)? thank you

Help with restart...

February 17 2009 ralperin 24

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

how to plot the expression...

February 16 2009 grigxc 84
I got an expression f:=R^3/(z^2+R^2)^(3/2); and would like to plot f as a function of (z/R), not z. Here R is a parameter. Could someone give me a hand?

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

polynomials in Maple...

February 15 2009 mark24 24

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...

page numbers...

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

If I have a set of numbers,

1, 2, 3, 4, 5

for example, how do I compute their mean?

How do I compute their standard deviation?

I am trying to avoid explicitly recopying cutting and pasting

my data over and over again, such as

a:= (1 + 2 + 3 + 4 +5 )/ 5;

sdev: = sqrt( (a-1)^2 + (a-2)^2 etc.

My REAL question is: WHERE in Maple 11 Help is an example shown anywhere of an explicit finite data set of numbers, such as 1, 2, 3, 4,5, or a set of pairs of numbers (2,3), (4,5) etc 

hey, i really need to integrate this equation for my calc class and i looked it up on an integral calculator online, and got some gigantic answer with logs and arctans... if you could show me the steps for this i wud gr8ly appreciate it!!!

Hi, sorry to open a new thread but the last one just got a bit too messy.

mathbin.net/5767 - What I want to do.

mathbin.net/5850 - What I have tried to do so far.

 

Any help on this would be greatly appreciated.  Thanks
