## how to complex plot this function?...

complexpoint run a long time
there is no option numpoints in complexplot, how to fasten it?

Lee := (-1+Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x))/(Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x));
complexplot(Lee, x = 0 .. 1);
Lee := Re(-1+Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x))/(Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x));
plot(Lee, x = 0 .. 2, numpoints = 5);
Lee := Im(-1+Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x))/(Int(exp(LambertW(1/(-1+t))*(-1+t)), t=1..x));
plot(Lee, x = 0 .. 2, numpoints = 5);

## Plotting Szego curve...

I want to plot a curve of the form |z*e^(1-z)| = 1 (the Szego curve). I am not sure how to call complexplot() to make this happen. Just calling complexplot(abs(z*exp(1-z)) = 1) does not work, and I don't know what else to specify. Any help?

## Trouble plotting complex equation....

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

For the life of me I can not get maple to plot this equation.  I have poured over various resources and it simply isn't working.  I have gone so far as to use SIMPLIFY and even  Re(circuitSix) and Im(circuitSix) yet still get only errors.  Any insight would be appreciated.

## Graph for stability analysis...

can anybody help me..? why my graph not come out? Is that any mistake in my coding?

## stability of the scheme...

i want to plot the graph based on this equation to know the stability of this equation :

y := A*(1/x+x*exp(-2*sqrt(-1)*b))+4*sin(h)^2*(2*exp(-sqrt(-1)*b)-3*sin(h)^2*x^(-sin(h))*exp(sqrt(-1)*b*(-sin(h)-1))+3*x^(-sin(h))*exp(sqrt(-1)*b*(-sin(h)-1)))/(3*(1-r))-exp(-2*sqrt(-1)*b)/x-x;

with A = (1+r)/(1-r), r = (1/3)*sin(h)^2, b = m*Pi*h, m = 1, h=0.05

can somebody help me..??

## Some problems with compexplot...

Help me with this:

I have a differential equation:  s:= diff(h(t),t) = -0.1738137398e-2/sqrt(2.8-h(t))

Solution is: h(t) = 14/5-(1/100000000)*2607206097^(2/3)*t^(2/3), h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)-(1/2*I)*sqrt(3)*2607206097^(1/3)*t^(1/3))^2, h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)+(1/2*I)*sqrt(3)*2607206097^(1/3)*t^(1/3))^2

And i have to need a plot... so i use complexplot and recive a mesage:

Error, (in plots:-complexplot) invalid input: `plots/complexplot` expects its 2nd argument, r, to be of type {range, name = range}, but received h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)-((1/2)*I)*3^(1/2)*2607206097^(1/3)*t^(1/3))^2

Help me if you can!! Thank you so much!!!

## Plotting complex roots of a polynomial...

I've used fsolve in Maple 6 to find the roots (real and complex) of a polynomial.  I'd like to create a plot showing the location of those roots in the complex plane.  How can I do this?

## Complex dispersion relation...

I have a problem related to solving the complex equation of dispersion relation.

In the plots some modes are missed. I dont know whay?

Is possible to help me? (m0^2<0).

restart;
with(plots):
rrr:=proc()
local ce,c0,ve,va,cte,ct,me,m0,DT,n,EQ,i;
ce:=6.2;c0:=0.25;ve:=5.25;ck:=1.06;ct:=0.243; cte:=2.515;
me:=sqrt(((ce^2-v^2)*(ve^2-v^2)/((ce^2+ve^2)*(cte^2-v^2))));
m0:=sqrt((c0^2-v^2)*(1-v^2)/((c0^2+1)*(ct^2-v^2)));
