Let a complex number (z) = 1/1+i
now,
z = 1/2 -i/2
so real part of z = x = 1/2
Imaginary part of z = y = 1/2
∴
Argument = tan⁻¹(y/x)
now,
z = 1/2 -i/2
so real part of z = x = 1/2
Imaginary part of z = y = 1/2
∴
Argument = tan⁻¹(y/x)

Answer:
1/√2
Step-by-step explanation:
1st step by rationalization : we get (1-i)/2 = 1/2 - i/2
2nd step comparing 1/2 - i/2 with x+iy we get x=1/2 & y=1/2
3rd step put the value of x & y in √(x²+y²) and
1/√2 is obtained
