Q. Find the argument of the complex number 3+3i in the interval 0≤θ<2π.Express your answer in terms of π.Answer:
Calculate Angle θ: To find the argument of the complex number 3+3i, we need to calculate the angle θ that the line connecting the origin to the point (3,3) makes with the positive x-axis in the complex plane. The argument is given by θ=arctan(real partimaginary part).
Find Arctan: Calculate the arctan of the imaginary part divided by the real part: arctan(3/3).
Identify Triangle Angle: Recognize that arctan(3/3) corresponds to the angle whose tangent is 3/3. This is a well-known angle in a 30-60-90 right triangle, where the angle opposite the side with length 3 is 60 degrees or π/3 radians.
Determine Final Argument: Since the complex number 3+3i is in the first quadrant (both real and imaginary parts are positive), the argument θ is simply π/3.
