latex of acos

[pragma]

hi, im new to sage :)

the latex output of arccos(x), arcsin etc. is

\cos^{-1} \left( x \right)

can i change this

\arccos


sry. for my english

[pragma]

ive tried this but it doesnt seem to do the job:

class c_arccos(sage.calculus.calculus.Function_arccos):
def __init__(self):
pass
def _latex_(self):
return "\\arccos"

p_arccos = c_arccos()

print latex(p_arccos(1/3))
print latex(p_arccos)

#############
#outputs:
############

\cos^{-1} \left( \frac{1}{3} \right)
\arccos

the first line still outputs \cos^{-1} instead of arccos

This seems to work:

sage: sage.calculus.calculus.Function_arccos._latex_ = lambda self : "\
\arccos"
sage: latex(arccos(1/3))
\arccos \left( \frac{1}{3} \right)

Best,
