In polar representation, a complex number is denoted in terms of two variables namely r and ϑ, where r is the modulus of complex number and ϑ is the angle with the positive direction of x-axis. Polar coordinates expresses the location of a point as (r, ϑ).
Find the polar form and represent graphically the complex number 7 - 5j.
x = 7 y = 5
Complex Number to Polar Form (z)
r = 8.602
ϑ = tan-1 (5 / 7) ϑ = 36°
(z) = 8.602 ( cos 36° + i sin 36°) Hence the polar representation value of complex number is calculated.
