Regarding the arcsine function and the complex variables approach:
z = sin(w)
w = -i*ln(iz +/- SQRT(1-z^2))
I'm trying to plug in numbers for z and "turn the crank" and get back the angle.
Meaning, if z = 0.5, the equation should yield 0.5236 (30 degrees) and if z = 0.707, I should get 0.7854 (45 degrees).
I've tried to do this in Excel. - no luck
I was assuming the "i" terms shifted things ?perhaps by PI/2? - no combination has worked.
How does this equation yield arcsine values? How do I turn the crank and handle the "i" terms.
Thanks
