what the difference between the phase and arctan?
조회 수: 55 (최근 30일)
I know (if I am correct ) that tan^-1(y/x) = arctan(y/x) =atan(y/x) = atan2(y,x) we use these expression to find the angle (theta) that calculateing from the positive real axis to the vector between the origen and the point z.
I am really confuse with the phase(z) , I read that
the phase(z)= arctan(y/x) whih the diference that ,
arctan takes values in ]−π/2,π/2[ while the phase is generally defined over ]−π,π].
Is this correct please?
I appriciate any help
