Thank you!!

Thank you very much for the tips!!!

It was a very interesting and helpful video!!!

Kjell

NO! I am looking for a numeric solution.Grid with mesh points!!

Kjell

Yes, I mean scrolling the help page. I use the mouse wheel and/or moving the mouse.

Same result. Look likes Maple is shifting position stepwise and not even smooth!!

Kjell

Thank you for quick answer.

How to do that correction?? I have already limit for x=-3..3 and y=-3...3

I thing I have to do a correction in the program!!

Regards

Kjell

 

R := implicitplot([x = -3/4, x = -1/3, x = 1/3, x = 3/4, y = -3/4, y = -1/3, y = 1/3, y = 3/4], x = -3 .. 3, y = -3 .. 3, color = red, scaling = constrained, gridrefine = 3); NULL; z := x + y*I; NULL; F := plottools:-transform(unapply(evalc([(Re, Im)(1/z)]), x, y)); NULL; A := plots:-display();

Yes!

 

complex displacement: U=u₁+u₂*i

@Kitonum 

 

Thank you very much for the answer, but Maple gave no solution

 

Here is the full heat equation

diff(u(x,t),t)=3*diff(u(x,t),x,x)

t more than 0

x from 0 to Pi

diff(u(0,t),x)=0,diff(u(Pi,t),x)=0

u(x,0)=0

Can you help?
