@Carl Love No, x is not a constant and 0<x<1, 0<t<1.  I have no idea about color levels.

@vv ok but how can i show the

It has to give it. My differential equation longer and complex so simplification is not what I want.

## @vv Firstly, thank you for your rep...

@vv Firstly, thank you for your reply. My problem starts with applying this to the differential equation

(my approach requirement)

solve(%, f[3](x));
After these commands I expect it to give

f[3](x)=

Can you look at the maple file?

@vv thank you for your answer.  I am using alpha (using palette) but gives alpha~.

@Kitonum ok but i want to see value of t on the graphic.

Thank you very much Dear @Ramakrishnan.

Actually my question was very simple because i wanted to plot a function u(x,y,z,t) that is a wave solution of partial differential equation. x,y,z are coordinates and t is a time variable. Finally i used plot3d command and my problem disappeared.

Thank you  for  your  effort.  Best regards.

i tried to pdsolve but it gave solutions depend on (x,t). But i want to solve u0,u1,.. depend on f(x,t).

@tomleslie i wanted to find lambda symmetries, integrating factors, linearization transformations for ordinary differential equations but it did not.
