part b

[rose musk]

Part B also wants a suitable range of values for x. I'm not sure how to do that.

Could anyone please assist me in this.

Cheers

say w = z + 3 + 2i
now the range of w that has an argument of 3π/4 is a ray from 0
now, z has the same range, just translated 3 + 2i

wait did you already solve a

[rose musk]

Yea I done a

[alpine stone]

basically since it's only half of a line, it should be x < some value

[rose musk]

All the time?

[alpine stone]

like z will satisfy it if and only if x < some value

as you can see that arg(w) = 3π/4 points left

[rose musk]

Right

I understand

[alpine stone]

and arg(0) is undefined so it has an open end
