Dear Sympy developers,
This is not a serious issue, but I wanted to flag it. According to the
documentation (and IMO correctly):
acos(x) = asec(1/x)
So I was surprised to see the contrast between:
>>> acos(Rational(1,2))
pi/3
>>> asec(Rational(2,1))
asec(2)
I would expect the previous line to return pi/3. Here is another
example of this:
>>> acos(sqrt(2)/2)
pi/4
>>> asec(2/sqrt(2))
asec(sqrt(2))
I would expect the previous line to return pi/4.
Cheers,
Bruce
