How Do You Find The Principal Argument?
How Do You Find The Principal Argument? The principal value Arg(z) of a complex number z=x+iy is normally given by Θ=arctan(yx), where y/x is the slope, and arctan converts slope to angle. But this is correct only when x>0, so the quotient is defined and the angle lies between −π/2 and π/2. What is mean
