複素数の計算
1  実部と虚部
2  四則と累乗
3  絶対値と偏角

1  実部と虚部

a=2;b=3;
z=a+I B

zz=4+5 I;
Re[zz]
Im[zz]

2  四則と累乗

\(a = \(-1\) + 2\ I; 
b = 3 + 4\ I; 
c = \(\@3 + I\)\/2; 
a + b\)a - ba ba/b\(For[n = 2, n <= 12, \(n++\), 
	\ \ Print[n, "  ", Expand[c^n]]]
      \)

3  絶対値と偏角

a = -1 + 2 I; b = 3 + 4 I; Abs[a]Abs[b]Arg[a]Arg[b]Conjugate[a]
