## solve numerically with boundary conditio...

Maple 15

Hi dear friends

I want to solve this equation with the foloowing boyndary conditions with maple. please help me to solve it

The nonlinear equation is:

F' ' ' +27*F*F' '=0

And boundary conditions are:

F' (infinity)=1

F' (-infinity)=0

F (-infinity)=0

## eliminating noise...

Maple 15

hi

I have 10 equations and the summation of them will give me the answer but each of them have small numeric noises and the sumation of them makes the final result inaccurate.  For example the first equation is

## over defined problem...

Maple 15

Have to solve and ODE in the domain of [-infnity +infinity ] via specific analytical method but due to some restrictions it could not be solved. In order to solve it, I have separated the domain into [-infinity 0 ] and [0 infinity]. So, I have to add some boundary values at x=0 to the problem. Assuming the solution of the mentioned ODE in  [-infinity 0 ] is g(x) and in [0 infinity]  is f(x), I added the boundary values of f(0)=g(0)=a and f ' (0)=b and obtained f(x...

## different answeres for a unit code !!!...

Maple 15

hey

I have wired problems with maple !!!

I run a code twice, I get 2 different answers !!!

I have uploaded the code ! just run it twicw and see the numerical values of alpha and beta at the end ! new_idea_gf.mw

## Ploting 2 vectors...

Maple 15

Dear friends

I want to plot a function with these coordinates in x and y directions where:

x=(0,0.0150754,0.0376884,0.0829146,0.0527638,0.120603,0.173367,0.203518,0.241206,0.286432,

0.316583,0.354271,0.39196,0.437186,0.474874,0.550251,0.58794,0.625628,0.678392,0.746231,

0.708543,0.81407,0.949749,1.1005,1.17588,1.33417,1.59045,1.91457,2.25377)

and

y=(1, 1.20603, 1.53769, 1.6, 1.77889, 2.74372, 3.49749, 3.9196, 4.43216,...
