Question

1 - i
1 + i
find the modulus and amplitude of this​

Answer 1

Step-by-step explanation:

First we solve 1+i/1-i

Let

z= 1+i/1-i

Rationalizing the same

1+i/1-i * 1+i/ 1+i

=(1+i)(1+i)/(1-i)(1+i)

(1- i) (1+t)

Using (a - b)(a + b) = a2-b²

=(1+i)²/(1)²-(i)²

(1)-(0)

Using (a +b)²=a²+b² + 2ab

(1)²+ (i)² +2i/(1)² - (i)²
