Here are some examples of trigonometry and arithmetic with complex numbers:
Evaluate sin (2 +
i

c
k
Result is 9.1545 –
i
4.1689.
Evaluate the expression
z
1
÷
(z
2
+ z
3
),
where z
1
= 23 +
i
13, z
2
= –2 +
i
z
3
= 4 –
i
3
Since the stack can retain only two complex numbers at a time, perform the
calculation as
z
1
×
[1
÷
(z
2
+ z
3
)]
