Question

4 - 3i . solve this problem​

Answer 1

Answer:

Complex number

POLAR FORM=5(cos( -tan⁻¹ 3/4)+i sin( -tan⁻¹ 3/4))

Step-by-step explanation:

This is a form of complex number. A complex number is one which has a real part as well as the imaginary part called iota, denoted by i.

These numbers have a set of rules of there own.

They are not represented on Cartesian plane but rather have a complex plane.

They can also be represented in polar form r(cosθ+i sinθ)

POLAR FORM OF THE NUMBER GIVEN-

r=√x²+y²

r=√4²+3²

r=√25

r=5

θ=tan⁻¹ y/x

θ= -tan⁻¹ 3/4

5(cos( -tan⁻¹ 3/4)+i sin( -tan⁻¹ 3/4))
