hi

i want save result in text file?

how i can do it?

for example eta and F(eta) in two  column

sample file is attache.

printf.mw

txtop1.txt

sample for save results::::

eta                     F(eta)

0.00000000, 0.00000000
0.10000000, 0.00096663
0.20000000, 0.00373543
0.30000000, 0.00810907

hi every body...

general solution of six order differential equation for example following equation

diff(w(x), x, x, x, x, x, x)+A*(diff(w(x), x, x, x, x))+B*(diff(w(x), x, x))+(-chi*omega^2+C)*w(x) = 0

is 

w := C1*sinh(upsilon*x)+C2*cosh(upsilon*x)+C3*sin(kappa*x)+C4*cos(kappa*x)+C5*sin(varsigma*x)+C6*cos(varsigma*x)

??

OR

w := C1*(cosh(upsilon*x)-sinh(upsilon*x))+C2*(cosh(upsilon*x)+sinh(upsilon*x))+C3*(cosh(kappa*x)-sinh(kappa*x))+C4*(cosh(kappa*x)+sinh(kappa*x))+C5*(cosh(varsigma*x)-sinh(varsigma*x))+C6*(cosh(varsigma*x)+sinh(varsigma*x))

or another form? is correct both of them or no??

please see maple attaced file.

please help me

thanks...

hi ..how i can rewrite answer in compressive format. that result seen readible and incomplex.for example how i can use change of variable, in order to final result has a short format...

thanks1.mw
