Question
#7 Please choose the correct answer. Show your solutions.
Note: When you encounter a
negative r in polar form, example
-5<50°, some scientific calculators
cannot distinguish it, just add or
subtract 180 to the angle to
eliminate the negative magnitude, so
5<(50+180) or 5<50-180)
Multiply (4 + j6) * 9<54°
in rectangular form, -22 +j60.87
NFTOC
in rectangular form, -22 - j60.87
in polar form, 64.90-110.31°
in rectangular form, 22 - j60.87
in polar form, 64.72<-70.13°
in polar form, 64.72<-109.87
in exponential form, 64.90e^(j110.31°)
or 64.90e^(j1.925 rad)
