Answer:
in degrees the answer is 5 (cos 270 + i sin 270)
in radians the answer is 5 (cos (3pi/2) + i sin (3pi/2))
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
Imma answer this because I don’t want this to get deleted for not bein answered and there free point who wouldn’t want them, lol :)
