## table of two on maple...

I want to generate table of 2 , how can i do this?

## compute the error and op function...

Hello,

Questions

1)  Can we compute the error  ( x(t-2*Pi) - x(t) )  without plotting  abs(  x( t-2*Pi ) - x(t) ) ?

i.e. using norm 1, 2 or infinity  ?

2)  what is op( [ a, b, c] , F ),  where F is a piecewise function ?

## How do I use these 2 lines to find the distance be...

Please help me solve this question using maple (need the steps in solving).

## How to draw these geometric objects?...

Hi, there

How can I draw the excircles, incircles,circumcircle and their centers of a triangle simultaneously with maple13 in a geometric plot? please specify the commands.

many thanks for your help

## Error when dsolving...

Been working on a diffy q project, new to maple here. Any help is appreciated. Keep getting a similar error.

"Error, (in dsolve/numeric/type_check) insufficient initial/boundary value information for procedure defined problem"

I thought I gave it initial values?

## Bifurcation plot for ODE system with delay...

Consider the following dynamical systems with time delay:

diff(x(t), t) = y(t)-bx(t)^3+ax(t)^2-z(t-tau)+I

diff(y(t), t) = c-dx(t)^2-y(t)

diff(z(t), t) = r(s(x-beta)-z(t))

Here the values of the parameters are a = 3, b = 1, c = 1, d = 5, s = 4, beta = 1.6, r = 0.6e-2, I = 3.0

How to write code for bifurcation plot for the above differential equations with delay.

Delay as taken as bifurcation parameter.

Reply message is very useful.

## Solar System Project Code Help...

solarsysem.mw Sorry for the repost but this is my newest document.

I have to create a solar system model on maple by defining a force equation then using the seq function to create a diffeq and then solving those differential equations using the initial conditions with the sun at (0, 0, 0) in xyz coordinates.

It works until my last "ic1" entry and I get an error in dsolve/numeric/process_input

I'm pretty desperate, I'll appreciate any help I can get

## Can 'for' be coded in Components? ...

Here is my command and i will use to make the user interface.

Orginal:

for i to l do

for j from x to y do

block[i][j] := 1-block[i][j]

end do;

c_block[i] := block[i];

c_block[i] := parse(cat(c_block[i][]))

end do

Can someone help me to edit my command so that i can write it in Click Edit Action for a button? thank you.

Do(for i from 1 to %l do)
Do(for j from x to y do)
Do(block[i][j] = 1-block[i][j]);
end do);
Do(c_block[i] := block[i]);
Do( c_block[i] := parse(cat(c_block[i][])));
end do);

## skeching f'(x) by all the points (x,f'(x)) when we...

How I can write a procedure in Maple 18 that it receives:

Inputs: function f(x) and real unmbers a and b (as interval [a,b]) and natural unmber n

then devides interval [a,b] to n subinterval and computes f'(a), f'(a+(b-a)/n), f'(a+2(b-a)/n),..., and f'(a+n(b-a)/n)=f'(b)

and

showes at output: graph f(x) and all points [a,f'(a)], [a+(b-a)/n, f'(a+(b-a)/n)],[a+2(b-a)/n, f'(a+2(b-a)/n)]..., and [a+n(b-a)/n,f'(a+n(b-a)/n)] on a coordinate plane x-y

## Help with MATLAB code...

Hello

I am a student of an engineering career

The math teacher is going to ask us to solve some exercises Matlab

The teacher is very hard and explains nothing of Matlab in class

We must learn to use the program on our own viewing internet watching tutorials

I was wondering if somebody could help solve some exercises.

Are only three exercises which are imposible to me

I would appreciate it greatly.

Thank you

## Connecting Two Lines Piecewise (ASAP)...

This is for the infamous Calc 2 Goblet Maple Project

I have tried everything changed all the numbers and got nowhere or worse results. The only thing that accurately works is the example project:

(0, 1.5) and end at (0.5, 0.2). which equals f1(x)=-2.6x+1.5

and f2:=x->0.2+0.05*sin(2*(x-0.5)) which is really 0.2+0.05sin(2x-1)

The goal is to change the example project so it becomes something of my own creation.

When I change f2:=x->0.4+0.05*sin(2*x-0.5)) it is at least attached but forms a sharp dip down first then connects at the point when it should be smooth curve. It seems you can do anything to the other curve

f3:=x->a*x^3+b*x^2+c*x+d;
x -> a x^3 + b x^2 + c x + d

connection1:=f3(5.5)=f2(5.5);
166.375 a + 30.25 b + 5.5 c + d = 0.3727989445

arc1:=f3(7)=1;
343 a + 49 b + 7 c + d = 1

arc2:=f3(7.5)=0.9;
421.875 a + 56.25 b + 7.5 c + d = 0.9

arc3:=f3(9)=1.6;
729 a + 81 b + 9 c + d = 1.6

values:=solve({eq1,eq2,eq3,eq4},{a,b,c,d});

F:=x->piecewise(x<0.5,f1(x),x>=0.5 and x<5.5,f2(x),x>=5.5,f3(x));

plot(F(x),x=0..9,y=0..4,scaling=constrained);

So how can this be fixed?

## How to convert a word to binary number?...

Hello, anyone know how to convert a word to 8 bits binary number ?

For example:

Here is my code:

message:=Hello
m:=convert(message,bytes);

>m:=[104,101,108,108,111]

with(Bits):

for i from 1 to 5 do:
mb[i]:=Split(m[i]);

end do;

>mb[1]:=[0,0,0,1,0,1,1] mb[2]:=[1,0,1,0,0,1,1] mb[3]:=[0,0,1,1,0,1,1] mb[4]:=[0,0,1,1,0,1,1]

mb[5]:=[1,1,1,1,0,1,1]

Anycommand can add additional one column when split the words into binary to form 8 bit in each row? Any help will be highly appreciated. Thank you.
