Given the equations, which of the following represents z1 * z2? Using the same values in #6, which of the following represents z1/z2 in standard form? The selected answers are incorrect.

First Attachment : Option A,

Second Attachment : Option C

Step-by-step explanation:

We are given that,

z₁ = and z₂ =

Therefore if we want to determine z₁( z₂ ), we would have to find the trigonometric form of the following expression,

( Combine expressions )

=

( Let's now add , further simplifying this expression )

( Substitute )

And therefore the correct solution would be option a, for the first attachment.

______________________________________________

For this second attachment, we would have to solve for the following expression,

From which we know that cos(π/6) = √3 / 2, sin(π/6) = 1 / 2, cos(π/3) = 1 / 2, and sin(π/3) = √3 / 2. Therefore,

Our solution for the second attachment will be option c.
