Find the modulus and arguments of 1/1+i - Brainly

Web4 feb. 2024 · modulus of a complex number Quick Reference If z is a complex number and z = x + yi, the modulus of z, denoted by z (read as ‘mod z ’), is equal to (As always, the sign √means the non-negative square root.) If z is represented by the point P in the complex plane, the modulus of z equals the distance OP . WebTherefore the condition ∣z∣=1 is equivalent to x 2+y 2=1. Now z+1z−1= x+iy+1x+iy−1 = (x+1+iy)(x+1−iy)(x−1+iy)(x+1−iy) = (x+1) 2+y 2(x 2+y 2−1)+2iy= (x+1) 2+y 22iy by (1) Hence z+1z−1 is purely imaginary when ∣z∣=1 provided z =−1. When z=1, we have z+1z−1=0. parramatta lga demographics
