Dear all

I have a fourth-order PDEs, with some boundary condition, I would like to compute an explicit solution or plot the solution in the interval [0,2]


 Dear all

Is there a nice idea to determine the Lyapunov function of the following system

Some parameters used in the code:

b fixed parameter

a any parameter in R

Many thanks for your help



If I know the direction of up and down

how to control normal distribution to fill in missing data to the direction I want in maple?

just like fill in missing pixel in bitmap file.

Hi all;

I need to compute the stabilizing feedback for the system of nonlinear ODEs


Many thanks for your help

Second terms coefficient = 2/3*x when (....)^2

9/16*x^2 when (...)^3

64/125*x^3 when (...)^4


Which Bernstein has these result?

Which limit function of x^n = (n^(n-1))/((n+1)^(n-1))*x^(n-1)?

how to find and calculate?



Variable disappear after read file and then pass parameter to create thread


How to read and write video file in maple?

i want to read one video file and then manipulate this to another file and then play two files to compare in maple

if maple 12 can not , which version can do?

How i convert the following mathematica code to Maple

f1[t^m_] := Gamma [m + 1] t^(m - a[t]) /Gamma[m + 1 + a[t]];
f1[t] := Gamma [2] t^(1 - a[t]) /Gamma[2 + a[t]];

f1[p_Plus] := Map[f1, p]
f1[c_*f_] := c*f1[f] /; FreeQ[c, t]
f1[c_] := 0 /; FreeQ[c, t]

f1[x^2*t^2 + t + x]


t^(1 - a[t])/Gamma[2 + a[t]] + (2 t^(2 - a[t]) x^2)/Gamma[3 + a[t]]

Plot([x^2, subs(x=0, 2*x)], axis[1]=[color=white]);

can not find the y=0 this red line

how to plot y=x^2 and x = 0 on the same graph to show the slope at x=0 ?

How to derive from n*x^(n-1) to limit definition ?

How to proof exp(x) is transcendental function without using calculus?

How to convert diff(f(t),t) + diff(g(t),t)

to diff(t(f,g), f)+ diff(t(f,g), g)


How to cmaple or mw file maple dualaxisplot output to jpeg file after press and run?

How to cmaple print int(f(x),x) after append to text command instead of /


I use append and cmaple to run

originally can See result in real time even if open text file

but suddenly text file become 0KB

when I copy text file and paste 

0 KB become 3 KB 

but the program can not further output to text file and no error shown
