Talk:Arcsecant Logarithmic Formulation

Looking at Spiegel's "Theory and Problems of Complex Variables" I see he gives:

$\dfrac 1 i \map \ln {\dfrac {1 + \sqrt {1 - z^2} } z}$

which arises:

a) by putting the equation given here over common denominator and simplifying

b) using a simpler form of the arccosine:

$\dfrac 1 i \map \ln {z + \sqrt {z^2 - 1} }$

which in turn arises by changing the sign of the radicand before rooting it.

I propose that if we can, we should use these simpler forms.

... I have actually already taken it upon myself to simplify the Arccosine Logarithmic Formulation as suggested. --prime mover (talk) 17:33, 28 October 2019 (EDT)
