as sided to the catalanization one: .
Zum beispiel: Enter
series(4 (4-x)^(3/2)-12 x sqrt(4-x) – 12 x^(3/2) arctan(sqrt( x/(4-x) )))/(4-x)^(5/2)
in a wolframalpha window.
I would like to add that the grasping of the fundamental sense for these objects and properties, are implanted around the generalization of calculus: differential forms and its applications…
the phrase was awarded with a Nice-Answer badge, which supports the fight for the differential form formalism… : )
