Different Taylor expansions for equivalent expressions

[lukamar]

Hi,
There is something wrong with series/taylor command. When I enter

Code : Tout sélectionner

series(cot(x)^2,x=0,1)

I get \(\frac{1}{x^{2}}-\frac{2}{3}+x^{2} \mathrm{order\_size}\left(x\right)\) as expected, but when I enter

Code : Tout sélectionner

series(cos(x)^2/sin(x)^2,x=0,1)

only \(x^{2} \mathrm{order\_size}\left(x\right)\) is returned.

Very strange, the answer is correct at default order. I will investigate!
