## Can not open context menu...

Hello everyone! I have just started to using Maple 13. I want to solve complex eauation systems.

When I am working on Maple, If I write simple mathematical calculation and then press right click, the context menu open. However, I want to use solve command. Therefore I wrote an eauation after than press right click the context menu will not open.

What is the reason of this problem?

## Integral not evaluated...

## convergence issue while expansion of hypergeometri...

In the first one I used hypergeometric function where the number is converged. Now using the series expansion of hypergeometric function I rewrite the equation as in the 2nd and 3rd case. But here it is not converging. I expect the same answer as in the first case i.e 0.14042. Thank you

## how to get the output of the plots in rows and col...

any one can help me to get the output of the plot in 3 rows and 2 columns here is my codes. thanks in advance.

restart;
h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L1)*(z - d1 - L1))):
K1:=((4/h(z)^4)-(sin(alpha)/Gamma2)-h(z)^2+Nb*h(z)^4):
lambda:=unapply(Int(K1,z=0..1), Gamma2):
L1:=0.2:
d1:=0.2:
alpha:=Pi/6:
with(plots):
display
( Vector[row]
( [ seq
( plot
( [ seq
( eval(lambda(Gamma2), Nb=j),
j in [0.1,0.2,0.3]
)
],
delta2=0.02..0.1,
legend=[Nb=0.1,Nb=0.2,Nb=0.3],
labels=[typeset(`&delta;1`), typeset(conjugate(`&Delta;p`))],
title=typeset("Effect of ", ''alpha'', " when ", Gamma,"2=", Gamma2)
),
Gamma2 in [10,20,30,40,50,-10]
)
]
)
);

## how to remove error in plot display...

Hellow ,

any body can help me to remove the error from the plot, here is my codes .

Note. 1. *Title {Effect of alpha when 'Gamma2'=Gamma2}

2. *on the y axis i want  bar(deltap)

restart;

h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L1)*(z - d1 - L1))):
K1:=((4/h(z)^4)-(sin(alpha)/Gamma2)-h(z)^2+Nb*h(z)^4):
lambda:=unapply(Int(K1,z=0..1), Gamma2):
L1:=0.2:
d1:=0.2:
alpha:=Pi/6:
plots:-display(Vector[row]([seq(plot([seq(eval(lambda(Gamma2), Nb=j), j=[0.1,0.2,0.3])], delta2=0.02..0.1, legend=[Nb=0.1,Nb=0.2,Nb=0.3],labels = ["d1 ", "Dp"],labelfont = ["SYMBOL", 12], title=(Effect of alpha when 'Gamma2'=Gamma2)), Gamma2=[10,20,30])]),axes=boxed);

## height and width of plot in maple 13...

how to adjust the height and width of plot in maple 13

plot( x[3]^5, caption = typeset("\n A plot of %1.", x[3]^5), captionfont=[times, 20] );

## caption size and font in plot...

hellow,

can any body help me to  increase the size of the caption in maple plot

plot( x[3]^5, caption = typeset("A plot of %1.", x[3]^5) );

## extracting coefficients of exponential functions...

Consider for instance the following equation:

Eq:=(a-4)*exp(4*x)+(b+1)*exp(2*x)+(c-2)=0

How can I list the coefficients of the exponential functions and also solve the equation for the constant parameters

a, b, and c?

I tried

[coeffs(collect(lhs(EQ), exp), exp)] =~ 0;

but it did not work. Thank you for your help.

## fetch the dsolve event time ...

1) How can i get the event time. This example 0.69313.

2) I don't want to see the Warning.How can i do it?

`Warning, cannot evaluate the solution further right of .69314729, event #1 triggered a halt`

## dsolve with event...

Why this event dose'nt work ?
S(t) is a state , a parameter
dsolve(...,numeric,events = [[[s(t), a*arcsinh(2/a) < s(t)], halt]]);

## Having problems with expansion series (mtaylor)...

Good evening!!!

Let me briefly describe the problem I've faced recently.

The program (attached) deals with a rather complicated function f depending on parametrs eps1, eps2, eps3, eps4 and variable w. The aim is to expand the function f(w1) into Taylor series with respect to all parametrs (eps1, eps2, eps3, eps4) in order to study its asymptotic behavior as function depending only on k; 0<k<1.

I decided to use mtaylor-function for that problem, which (as I've understood) is the only one to be applied in such cases, but the result was rather unsatisfactory, an error:

Error, (in gcd/LinZip) input must be polynomials over the integers

Programm code: (1)-(12) only announcing functions....(((, see below
