Silence Resonance Posted December 5, 2010 Share Posted December 5, 2010 (edited) Two problems... 1. What is i to the power i? (hint: it's a real number!) 2. Give a good approximation* for i^i^i^... (hint: exponentiation is right-associative. That means x^y^z means x^(y^z), not (x^y^z.) *for grading purposes, I will define a "good approximation" of complex number x to be a number, z, such that |x-z|<0.01 Edited December 5, 2010 by Silence Resonance Link to comment Share on other sites More sharing options...
Bignose Posted December 6, 2010 Share Posted December 6, 2010 (edited) [math]e^{-\frac{\pi}{2}} \approx [/math] 0.20787957635076193 actually any of [math]e^{-\frac{\pi}{2}-2\pi N} [/math] for any integer N is also a valid answer.
