Q
Q: If z = 1 + √3i, what is the argument of z? (2015)
Solution:
The argument is given by tan^(-1)(√3/1) = π/3.
Steps: 6
Show Steps
Step 1: Identify the complex number z, which is given as z = 1 + √3i.
Step 2: Recognize that the real part of z is 1 and the imaginary part is √3.
Step 3: Use the formula for the argument of a complex number, which is given by the tangent function: argument = tan^(-1)(imaginary part / real part).
Step 4: Substitute the values into the formula: argument = tan^(-1)(√3 / 1).
Step 5: Simplify the expression: argument = tan^(-1)(√3).
Step 6: Recall that tan(π/3) = √3, so the argument is π/3.
