Is there a document with all elementairy plottools commands to find?

i must construct a numberline and lines to e4xplain with a arrow and text under it.

with(Finance):
with(Statistics):
X:=RandomVariable(Binomial(nn, pp));
Drift(X);

How to listplot two vectors on the same graph?

That means having two lines.

f1 := -2*x1 - x2;
f2 := -x1 - 4*x2;
g1 := 2*x1 + 3*x2 - 6;
g2 := -x1;
g3 := -x2;
penalty := lambda1*Max(f1-M,0)+lambda2*Max(f2-M,0)+(M^2)*(max(g1,0) + max(g2,0) + max(g3,0));
M := 1;
k := 1;
s := 1;
lambda1 := 0.5;
lambda2 := 0.5;
with(Optimization):
Minimize(subs(lambda2=0.5, subs(lambda1=0.5, subs(M=1, penalty))));

correct answer for these parameters should be below, however, Minimize got error

when lambda1 = 0.5, lambda2 = 0.5
(x1, x2) = 1.551123, 0.965918
f(x1, x2) = (–4.068164, –5.414795);

in maple 12 or 15

assume 

result := Vector(10);

for i from 1 to 10 do

        result[i] := i;

od;

how to plot it against i?

after tried plot(result(x), x=1..10);

Hi all. I am using Maple 18.

1. How can I make maple NOT plot discontinuties with a vertical line? For example, plotting y=tan(x) displays vertical lines. Is there a setting to turn this off permanently?

2. When I type y=sin(x-Pi/2) and press enter, y = -cos(x) is displayed in blue. I am sure they are both the same thing, but I would like to see the expression that I typed, not an alternate expression that Maple wants to display.

3. Why do some expressions require a ; at the end, whilst others don't? Ie. y = sin(x) and y = 1+sin(x) do not, but y=2*sin(x) results in a "Warning, inserted missing semicolon at end of statement"

4. Is there a section on Mapleprimes(this site) where new users can ask questions? I would like to browse it to see what sort of problems other new Maples users have encountered. I am sure that my above questions may have been asked a few times over the years by newbies like myself.

Thanks in advance. :)

hi maple-friends !

for my work i have to solve a system of differential equations numerically - no problem with maple :-)

my problem: how can i get the resulting data of the numeric solutions in a file ?

(for example to use them with gnuplot)

what i have to do exactly ? i know just about writedata and readdata commands...

can anyone send me an example with a few comments ?

greetings,  kreso

With this contribution we opened a breach in the proper use of the program applied Thermodynamics.

Introducción_a_la_Termodinámica.mw     (in spanish)

How can I know the solution is correct??

Here is the code:

s := solve(sin(x^2) = 1/2);
test := subs(x = s[1], sin(x^2) = 1/2);

I am trying to produce a worksheet that will give me the two roots of a quadratic equation.

This is what I have:

As you can see, It's not giving me the right answers. What do I do?

Thanks,

Paul

I see a document with maple graphics in it, but i don't see the maple code in the document.

Has the author protected his code ?
I like to see the maple code used for the document ..how to read this maple code?

Note: try to find answer on the Maple site , but no idea where to find thisinformation on how to set up a document..frustrating.  
 

hi,

i obtained values for h(t) and u(t) and i wana obtaine s(t) , i don't konw how can i do it

for h(t) and u(t) ,

sol1 := dsolve([4.00000000000000*u(t)^2*h(t)*(diff(diff(h(t), t), t))-8.00000000000000*h(t)^2*(427.2460938*u(t)+385620.1174/u(t)-25671.38673)^2+16.0000000000000*u(t)*h(t)*(427.2460938*u(t)+385620.1174/u(t)-25671.38673)*(diff(h(t), t))+(16406.2500000000*(-29.8200000000000+u(t)))*h(t)^2*(427.2460938*u(t)+385620.1174/u(t)-25671.38673)+7171.87500000000*u(t)*h(t)*(diff(h(t), t))-16406.2500000000*h(t)^2*(30-u(t))*(427.2460938*u(t)+385620.1174/u(t)-25671.38673)+u(t)^2*h(t)-0.225000000000000e-1+0.225000000000000e-1*(.997494986604054+.106105802501554*sin(t-1.5))^2+4.00000000000000*(h(t)*(427.2460938*u(t)+385620.1174/u(t)-25671.38673)+u(t)*(diff(h(t), t)))^2 = 0, diff(u(t), t) = 427.2460938*u(t)+385620.1174/u(t)-25671.38673, h(1.44) = 0.145e-4, (D(h))(1.44) = .12093, u(1.44) = .62], numeric)

and s(t) is , s(t)=1/r*d/dt(u(t)*h(t))

thanks.

Code was computed on two different PC:
1) Win 8.1, Maple 17.02 x64
2) Win 8.1, Maple 18.01 x64

In brief:

n:=3: 
Grid:-Seq('f(i)', i = 1 .. n): 

works well in Maple 17.02 but gives an error in Maple 18.01. Why?

However,

(j -> Grid:-Seq('f(i)', i = 1 .. j))(n):

works well for both Maple versions.

according to examples from Maple help page
http://www.maplesoft.com/support/help/Maple/view.aspx?path=Grid%2fSeq
we have to pass exactly 'f(i)' (not just f(i)) into Grid:-Seq(...). Why?

Why doesn't Digits:=30: work properly for Grid:-Seq(...)?

For details see attached file. Output was produced in Maple 17.02. In Maple 18.01 the output will differ.

Hello guys...

please help me to solve these equation.I have some equation with some boundary condition.

Why can't I have good results for it?

how can I have a good result with this method?
please help me to solve this multi equations multi variable.

I have a big expression with multiple terms. The expression is kind of :

expr = a*ln(u) + b*ln(u) + a*ln(v)+b*ln(v)

I want to factor ln(u) and ln(v) to get (a+b)*ln(u) + (a+b)*ln(v)

I tried factor(expr,ln(u)) but I get the error :
Error, (in factor) 2nd argument, ln(2*da+(4*da^2+4*d^2-4*da*Sigma[a]+Sigma[a]^2+Delta[b]^2)^(1/2)-Sigma[a]), is not a valid algebraic extension.

I tried without Delta[b] and Sigma[a] : deltab and sigmaa but it didn't work either.

Do you have an idea how to factor the many ln ?

Thanks,
Mathieu
