Horizontal the real axis and Vertical i axis. Let Z1, Z2 and Z3 represent three complex numbers in an Argand diagram.Z1 = 3+i, Z2 = 2+i and Z3 = 1 +i,Our angles of interest are the "Arguments" of these three complex numbers.  Now we know that if we multiply complex numbers then the Arguments gets added.I leave it to you to multiply Z1, Z2 and Z3. You will get the answer 10i. So the argument of the multiplication of the three numbers is π/2.Thus A + B + C = π/24) TrigonometryThe other solution is the one I already mentioned above using Trignometry and the property of the addition of two inverse tangents.A + B = tan^-1(1/3)+tan^-1(1/2) = π/4 = C------ Post added on [DATETIME="UT"]1717288036[/DATETIME]</blockquote>
