Assignment Submission Assignment, you submit answers by question by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer. Assignment Scoring Assignment submission is used for your score. The complex number z = -1 + i in polar form is z =. The complex number z = 2(cos(pi/6) + i sin(pi/6)) in rectangular form is z = ___________. The complex number graphed below can be expressed in rectangular form as z = or in polar form as z = _________.

the answer. Assignment Scoring Assignment submission is used for your score. The complex
number z = -1 + i in polar form is z =. The complex number z = 2(cos(pi/6) + i sin(pi/6)) in
rectangular form is z = ___________. The complex number graphed below can be expressed in
rectangular form as z = or in polar form as z = _________.
Solution
a)given z =-1+ 1i
r =[(-1)2+12]
r=2
=tan-1(1/-1)
=-tan-1(1/1)
=-(/4)
=(3/4)
z=2 [cos(3/4) +i sin(3/4)]
====================================
b)z=2 [cos(/6) +i sin(/6)]
z=2 [(3 /2) +i(1/2)]
z=3 +i1
z=3 +i
c) z =(1+ 1i)
z=2 [cos(/4) +i sin(/4)]
