Furthermore......what is a complex exponent?...........w/o using trig functions...........but the P theorum.......



Complex Exponentiation

DOWNLOAD Mathematica Notebook
complex number may be taken to the power of another complex number. In particular, complex exponentiation satisfies
 (a+bi)^(c+di)=(a^2+b^2)^((c+id)/2)e^(i(c+id)arg(a+ib)),
(1)
where arg(z) is the complex argument. Written explicitly in terms of real and imaginary parts,
 (a+bi)^(c+di)=(a^2+b^2)^(c/2)e^(-darg(a+ib))×{cos[carg(a+ib)+1/2dln(a^2+b^2)]+isin[carg(a+ib)+1/2dln(a^2+b^2)]}.
(2)
An explicit example of complex exponentiation is given by
 (1+i)^(1+i)=sqrt(2)e^(-pi/4)[cos(1/4pi+1/2ln2)+isin(1/4pi+1/2ln2)].
(3)
A complex number taken to a complex number can be real. In fact, the famous example
 i^i=e^(-pi/2)
