Question

If (π/3) and (π/4) are arguments of z1 and barz2 then the value of arg (z1 z2) is (A) (5 π/12) (B) (π/12) (C) (7 π/12) (D) (-π/12)

Tardigrade Admin · Accepted Answer

arg (z1 z2)= arg (z1) + arg (z2)=(π/3)-(π/4)=(π/12)

Q. If $\frac{π}{3}$ and $\frac{π}{4}$ are arguments of $z_{1}$ and $\overset{z}{ˉ}_{2}$ then the value of $ar g (z_{1} z_{2})$ is
