Thank you, don't make the calculation bigger, but more efficient.

That's what I understand from it.

@acer 
I can't manage to create such a nice short procedure like you do.

@acer 
Would it be correct to say that t and K are degree 1 and a number is degree 0  and both lineair ?

For a pde you can select lineair en not llinear terms by hand 

L := convert(expand(pde1), list, `+`)
lineair := L[1] + L[2]

A procedure , numeric, symbolic sphere equation for given sphere centre and 3 circles 

A phytagoras circles example

res := SphereFromSections([8, 4, 0], 4, 3, 5, symbolic = true, plot = true);
res[equation];
res[center], res[radius];

"Sphere equation: ", (x - 3.000000000)^2 + (y - 4.000000000)^2 + z^2 = 25.00000000

Ai says  , its ill posed?
At first, the Ai said that the task was impossible, but later AI said that it was possible.( again question)

The ai  is improved lately, and seems to be much better , making this is not a achievement

@AHSAN 

odeplot chooses its own (adaptive or fixed) sample points to draw a nice curve.

Difficulties with interpolation in dsol

Maple stores the numerical solution on an adaptive grid (mesh) — not on my fixed 9 y-values that I want.

That is why I get → Float(undefined) when I try calculate points.

There is no explicit function that is so easily known for the 5 graphs of the fraction coefficient to obtain the plot values.

@AHSAN 
 

That code does not work because the two tables are not filled.

The plot with 5 curves is drawn, so there are known y values, but the current code fails to place function values in the two tables shown.

@AHSAN 

It seems more practical to first create a function value table for 1 plot.

Does Maple have a procedure for this already ?

@AHSAN 
Maple 2025.1  gives right output table structure , but still not complete

@AHSAN 

I enclosed the same file again yesterday ( I must delete post ?) , so i go further with this one (intented for yesterday.). Must be further improved.
