Hi Everyone!

I want to export several Figures with Maple at the same time. I tried

with(plots):

for i from 1 to 5 do
interface(plotdevice=ps, plotoutput=`c:/test||i.eps`, plotoptions=`color,portrait,

od:

but it did not work. How can I create one file per Figure?

Thanks a lot,

Bernardo

 

If I try to solve the following differential equation with simbolic parameters:

IC := p(0) = condizIni

ode := diff(p(t), t) = (QIn-QOut-derV)/((1/Boil+1/Bwall+percair/(m*p(t)))*V)

func := rhs(dsolve({IC, ode}))

the result I get from Maple12 have the following member inside it:

LambertW(_Z7, _Z)

but I do not know what are _Z7 and _Z.

Where I can find the expression of these parameters?

Why Maple added these parameters?

I like the feature that permits the use of the dotted derivative, as it has the look and feel of the work that I am doing. However, when I enter, say, (x_dot + 1)^2 and invoke the expansion, I get x_dot(t)^2 +...

It's nice that Maple knows that x is a function of t, but I would like to avoid the clutter. How do I suppress the (t) so that all I see is x_dot^2?

I use Maple 11. Sometimes, the result become more then one when it run. Then the results are same. How to make it to give difference result?

Thanks.

 i have a project from my univercity an d i want to ask you how can i put maple into flash document so can you help cause i must give my project one month again thanx before

How can i avoid this error?

that happens 'cause I have 3 different solution for Vv:

> Vv3:=Re(solve(eq1,Vv)[3]);

 

The following program was created to determine a Hermite polynomial. Can anyone see where the error lies? Thanks!

 

restart; f:=x-> (x*(cos(x)))- ((x*x(sin(x/2))));
                 f := x -> x cos(x) - x x(sin(1/2 x))

                              fp := D(f)

 

I am trying to modify a solution to a non-homogeneous boundary value problem presented in Dr.

Hi everybody, one thing is not still clear to me about assume: for example  I have to find the solution of this simple equation:

e1 := q=ks*h^(5/3)*sqrt(If);

If i write solve(e1,h);   I get also all the complex solutions. I want just the real solution so i wrote:

assume(h::real);
solve(e1,h);

but I still have all the complex solutions. Why? I tried also  with assume(h::real,h>=0); but it's the same.

thanks

I need to input f(N,x)=summation{(-1)^(n+1)/n}sin(nx) N=1,3,5....infinity

Why gives Maple T.A. for the function

decimal(2,-0.625)

as an answer -0.62 instead of -0.63?

I could not find documentation on the decimal function. Where can I find it?

 

kind regards,

Problem: Find the value of k (k>1) such that the region enclosed by y=2lnx, y=0, and x=k has an area of 5 square units.

I'm figuring it should start out like this:

f:=->x2lnx;

then im figuring to plot it so i can get a look at the graph so i can guestimate what value for k would be 5 square units.

but what commands can i use to solve it exactly?

I cant remember how to find the intersection of two functions.

I know to first enter in the two functions (f(x) and g(x)).

Then I need to plot them...

But whats the command to find the point of intersection?

Hello Guys, I have this homework assignment which requires me to use Maple. Unfortunately, I'm new to this program, and frankly, have no clue how to use it. So I've been following this worksheet step-by-step and now it's telling me to plot inequalities using the plot assistant. May anyone please help me? It will be very much appreciated. Sample equation to graph: y>2 Thank you very much!
