The argument of a complex number is the direction of the number from the origin or the angle to the real axis. Sometimes this function is designated as atan2(a,b).
arg(a+bi) =
atan(b/a)
atan(b/a)+π
atan(b/a)-π
π/2
-π/2
not defined
, if a>0
, if a<0 and b≥0
, if a<0 and b<0
, if x=0 and y>0
, if x=0 and y<0
, if x=0 and y=0
Please enter the two values a and b of a complex number in the form a+bi, the argument will be calculated.
The calculators use . and , als decimal separators.
