Answer: 5 x ?
Step-by-step explanation:
Use the formula z=a+bi=|z|(cosθ+isinθ), with |z|=√(a²+b²), and tanθ=b/a<span>
in this case, a=0, b=-3 so </span>|z|=√0²+(-3)²)=3
tanθ=
, notice the denominator is 0, undefined, so the value of θ=π/2
Substitute the values of <span>θ=π/2</span> and <span>|z|=3</span>. into the formula, you'll get <span>3(cos(</span>
)+isin(
))
You are changing the sign on one so to keep an equilibrium you change the other sign too
