In sage-4.0.1, most of the primitive functions suffer from
inconsistence typsettings. For example:
{{{
f = arcsin
latex( f ); latex( f(x) ); latex( f(x,1) )
\sin^{-1}
\arcsin\left(x\right)
\mbox{\sin^{-1}}\left(x\right)
}}}
Note that the same function is being typeset differently. The additional
"\mbox" in third case (which has been reported in
#6268) will get resolved by #5711.
However, second case seems weird to me, given "class Function_arcsin"
(sage.functions.trig) clearly defines its
latex expression to be "\sin^{-1}". So it seems to be a pynac issue.
One can try following to see the issues for other functions
{{{
# Trigonometric functions
lst = [sin, cos, tan, cot, sec, csc, arcsin, arccos, arctan, arccot,
arcsec, arccsc]
# view
for fn in lst:
view( fn ); view( fn(x) ); view( fn(x,1) )
# latex
for fn in lst:
latex( fn ); latex( fn(x) ); latex( fn(x,1) )
}}}
and
{{{
# Hyperbolic functions
lst = [sinh, cosh, tanh, coth, sech, csch, arcsinh, arccosh, arctanh,
arccoth, arcsech, arccsch ]
# view
for fn in lst:
view( fn ); view( fn(x) ); view( fn(x,1) )
# latex
for fn in lst:
latex( fn ); latex( fn(x) ); latex( fn(x,1) )
}}}
It seems, out of these 24 functions, 18 functions suffer from
inconsistence typesetting.
