Question

find the modulus and argument of complex no 2i​

Answer 1

Answer:

Modulus = 2 and Argument = (tan^-1)2

Step-by-step explanation:

Modulus,

2i i.e., 0 + 2i

a= 0 b=2

Modulus = under root (a^2 +b^2)

Modulus = under root ( {0}^2 +{2}^2 )

= under root (4)

Modulus = 2

Argument,

Below A is an angle,

tanA = I b I / I a I

tanA = 2

A = (tan^-1)2
