Complex conjugate of z2=8(cos(7pi/6)+isin(7pi/6)))

Answer 1

@Hero @Michele_Laino @ganeshie8 @mathstudent55 @Nnesha @Loser66 @Luigi0210 @whpalmer4

Answer 2

My worksheet says /z subscript 2. Which I think means complex conjugate.

Answer 3

It gave me the z2 equation and just says /z2

Answer 4

okay, thanks for attempting to help :)

Answer 5

What does the x' and y' mean?

Answer 6

oh, gotcha

Answer 7

So the conjugate is 2 sqrt(7)?

Answer 8

Okay, thanks! That was pretty helpful.

Answer 9

*if* \( z_2=8\ (cos\frac {7 \pi}{6} \ + \ isin\frac{7\pi}{6})\), then \( \bar z_2=8\ (cos\frac {7 \pi}{6} \ - \ isin\frac{7\pi}{6})\)

Answer 10

Oh, so it only needs a subtraction?

Answer 11

@NotSephiroth
yes

\(z = x + i y\), \(\bar z = x - i y\)

Answer 12

or \(z = R e^{i \theta}\), \(\bar z = R e^{-i \theta}\)

Answer 13

Okay thanks!

Answer 14

that was really helpful!
