Complex Numbers b Evaluate tan 1 2j Solutionarg is a functio

Complex Numbers:

Solution

arg is a function operating on complexnumbers (visualized in a complex plane). It gives the angle between the positive real axis to the line joining the point to the origin

a point on img axis is 0 + 2i

tan(theta)= 2i

for that point 0 + 2i

theta = pi/2 (anwer)
