WebIf we extend this concept to complex numbers and also use the fact that i^2=-1, we can rewrite the pair of equations as e^ (-1) = cos (i) + i sin (i) and e^ (1) = cos (i) - i sin (i). Subtracting the second equation from the first equation and then dividing by 2i, we have sin (i) = [e^ (-1)-e^ (1)]/ (2i) = [- (1/e - e)/2]*i = [ (e - 1/e)/2]*i. reading winter wonderland contactWebSep 19, 2014 · Wataru.
