Question

Express the complex number z = -4+3i in polar form: r(cos⁡(θ)+i sin(θ)).

Answer 1

Answer:

5( cos(- 0.64)+$i$ sin(-0.64))

Step-by-step explanation:

Given:

z = -4+3i

$r=\sqrt{(-4)^2+3^2}= 5$

θ=$tan^-^1(\frac{3}{-4} ) = -0.64$

Polar form=r(cosθ+$i$ sinθ)=> 5( cos(- 0.64)+$i$ sin(-0.64))
