Points z1 & z2, are adjacent vertices of...

Points `z_1 & z_2`, are adjacent vertices of a regular octagon. The vertex `z_3` adjacent to `z_2` `(z_3!=z_1)`is represented by

Text Solution

Verified by Experts

`z_3-z_2=(z_1-z_2)e^(1(pm3/4pi))`
`z_3=z_2+(z_1-z_2)(-1/sqrt2pmi1/sqrt2)`
`z_3=z_2+(z_2-z_1)(1/sqrt2pmi1/sqrt2)`
option c is correct.
