Answer-If z=2+3i, then arg(z)=θ lies in which quadrant?

We are given a complex number z 2 3i We are to determine the quadrant in which the argument argz lies. The complex number zabi23i corresponds to the point 2,3 in the complex plane , where Real part 2 positive Imaginary part 3 positive So, the point lies in the first quadrant , where both real and imaginary parts are positive.
