Question

?

Answer 1

uh not really sure what 14 is asking but 13 and 15 are just the same two formulas from before

Answer 2

could you just post that chart one more time

Answer 3

so I can refer back to that

Answer 4

pi/5+7pi/6=41pi/30(New Theta)

Answer 5

good, now find r1r2

Answer 6

2-8=16?

Answer 7

2*8**

Answer 8

good

Answer 9

so

16[cos(41pi/30)]+isin [(41pi/30)]

Answer 10

good, then for 15 repeat with the division formula

make sure to get the order right, it's z1/z2

Answer 11

0.25[cos(-29pi/30)]+isin [(-29pi/30)]

Answer 12

good

for practical purposes it would be a good idea to re-define theta so it's positive so you just need to add 2pi to -29pi/30 to get 31pi/30

Answer 13

not really sure what convention your book/teacher prefers

Answer 14

Yeah I think I got it so you dont know what 14 would be :S

Answer 15

oh yeah for 14 the horizontal line just means the conjugate of z2

Answer 16

so just change the + sign to a - sign and copy the rest over

Answer 17

so -8and the rest stays the same

Answer 18

the + sign in the middle, not in front

Answer 19

oh in fron of Isin

Answer 20

so 8(cos(7pi/6)-i sin(7pi/6))
