Hello

Can I make a button with the code so it will execute the entire worksheet?

I have tried without sucess to run the

Equation manipulator.

I get the following error:

"

Error, (in Maplets:-Tools:-CleanElements) invalid input: op expects 1 or 2 arguments, but received 0

"

Do I have to load some package for it to run?

I have searched for a solution but can not find one.

Getting desperate.. anyone?

TIA

LWc

I want write loop for this code:

V := 24;

eq := {Eq2, Eq3};

ans := fsolve(eq, {a1 = 0, a3 = 0});

r := 0;

W1 := rhs(ans[1])*phi11(r)+rhs(ans[2])*phi21(r)

V and W1 is Variable, I change V and solve eq and determinen a1 and a3 after i calculated W1

I want write Loop for this,

can you help me????????/ 

%piecewise(``, x+y-2*z = 1, ``, 2*x+y-3*z = 5, ``, -x+y+z = 1); What does % here do?

I can find no help page to explain the functionality of the percent sign in this command and removing it produces an error. Please explain this.

Hi

How  can we draw diagrams in tripartite coordinate system?

Hello,

How to Factorize the coefficients of this matrix :

> A:=Matrix([[x^3+x-2,x^2+x],[x,x+1]]);

factor(A) does not work !

Thank you,

Gérard.

Hello,

I have the following list made with dsolve:

num_n := dsolve({c_i1, c_i2, Ecuacion_1, Ecuacion_2}, numeric, method = classical[rk4], {u(x), v(x)}, stepsize = .1);
proc(x_classical) ... end;
for i by .1 to 2 do num_n(i) end do;
[x = 1., u(x) = 1., diff(u(x), x) = 0., v(x) = 0., diff(v(x), x) = 1.]

...

But when i do :

u(1);

u(1)

Should be u(1)=1 and not u(1)=u(1).

Regards.

Carmelo.

I would like to ask your assistance in understanding the following Maple interaction which speaks for itself.

Best regards, Marko Riedel

H := 1/(2*m)*diff(f(q,P,t), q)^2 = -diff(f(q,P,t),t);
assume f = f1(q) + f2(t);
H := 1/(2*m)*diff(f1(q), q)^2 = -diff(f2(t),t);
dsolve(H);

set each side of equation be a constant E which is anticipated integration constant
how to solve to S = q*sqrt(2*m*E) - E*t

and

p = diff(S,q) = sqrt(2*m*E);
Q = diff(S,E) = q*m/sqrt(2*m*E) - t;

There is a desire to explore the process of filtration combustion. To do this, you must solve a system of differential equations in partial derivatives.
I write down all the equations.
Boundary conditions in Maple 2015.0 interpreted incorrectly.
I need to write like that:

given that:

It turns out so:

ie somewhere lost derivatives

,....

As in Maple record boundary conditions correct?

Thanking you in advance.

can maple 18 install in mobile phone Lumia 950?

Hello everyone. 

I can not calculate it here

Probably, the problem with the calculation of surface integrals. I would be grateful for any help.

Hi, 

The question: 

Create a table of the droplet´s range as a funstion of the initial velcity for v0=0.2..4 m/s in steps of 0.2 m/s, each with starting angle of 36 degree. What range of Reynolds numbers does this correspond to? Plot the result.   

I get the result for one of the v values, but struggling to get values for all the v-values. 

F_D:=proc(v::list) #force/mass
local k,vx,vy;
vx:=v[1];
vy:=v[2];
k:=-evalf(3*Pi*mu*d/m);        #common constant, calculated only one time
[k*vx,k*vy];                           #returns a vektor
end proc;

 
Euler:=proc(vo::list,h)             #using the Euler method to solve the equations
local vx,vy, F;
F:=F_D(vo);
vx:=vo[1]+h*F[1];
vy:=vo[2]+h*(F[2]-g);
[vx,vy];
end proc;

Hi all,

I want to know how we can have the result which is made in Maple in Latex in a good style... I must prepare a report of it today, but when I copy the result from Maple to Latex, there're a lot of things to edit, also the results that are obtained from Maple are a lot, so it's very difficult for me to type it in Latex...

Please help me

I have the solution to a heat PDE, v and the error esitmate u + cos(x+t) = v

I want to plot log v(1,t) as function of log u(1,t) in maple, but I seem to get an error:

Error, (in plot) unexpected option: ln(u(1, t))

I am attaching my code below.

How to fix this problem?

Thanks in advance.
