Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where,
and
,
is called the argument of z,
.
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5.
lies in 4th quadrant.
So, the trigonometric form is
7*9
b. 63
v=5 i=1
5+1+1= 7
x=10
10-1= 9
9*7= 63
Answer:
