Hi,
With the switch to pynac, the way we typeset arcsin and friends changed.
sage: version()
'Sage Version 4.0.1, Release Date: 2009-06-06'
sage: latex(arcsin(x))
\arcsin\left(x\right)
as opposed to:
sage: version()
'Sage Version 3.4.2, Release Date: 2009-05-05'
sage: latex(arcsin(x))
\sin^{-1} \left( x \right)
The new convention we got from GiNaC is also what Maple follows:
> latex(arcsin(x));
\arcsin \left( x \right)
However, MMA goes with the previous method:
In[1]:= TeXForm[ArcSin[x]]
Out[1]//TeXForm= \sin ^{-1}(x)
I think the previous convention is confusing, since it's not clear if
this is the inverse function, or a power. I.e., it's common to use
sin^2(x) to denote (sin(x))^2.
I thought we should vote before I make this change the new standard,
as a part of #6286.
My vote is for arcsin.
Cheers,
Burcin
