Question
If z=2+3i, then arg(z)=θ lies in which
quadrant?Solution
We are given a complex number: z =2+ 3i We are to determine the quadrant in which the argument θ=arg(z) lies. The complex number z=a+bi=2+3i corresponds to the point (2,3) in the complex plane , where:
- Real part = 2 (positive)
 - Imaginary part = 3 (positive)
