1Express the complex quotient (3 + 4i) / (1 - 2i) in standard rectangular form a + bi.
A.-1 + 2i
B.1 + 2i
C.-1 - 2i
D.2 - i
Explanation: To divide complex numbers, multiply the numerator and denominator by the complex conjugate of the denominator (1 + 2i): ((3 + 4i)(1 + 2i)) / ((1 - 2i)(1 + 2i)) = (3 + 6i + 4i + 8i^2) / (1 - 4i^2). Since i^2 = -1, the numerator is 3 + 10i - 8 = -5 + 10i, and the denominator is 1 - 4(-1) = 5. Dividing gives (-5 + 10i) / 5 = -1 + 2i.
2Find the modulus and principal argument of the complex number z = -1 - i√3, where Arg(z) ∈ (-π, π].
A.Modulus = 2, Argument = -2π/3
B.Modulus = 2, Argument = -π/3
C.Modulus = 4, Argument = -2π/3
D.Modulus = 2, Argument = 2π/3
Explanation: The modulus is |z| = √((-1)^2 + (-√3)^2) = √(1 + 3) = √4 = 2. Since both real and imaginary parts are negative, z lies in the third quadrant. The reference angle is α = arctan(|-√3| / |-1|) = arctan(√3) = π/3. In the principal range (-π, π], the argument in quadrant III is θ = -(π - α) = -(π - π/3) = -2π/3.
3Which of the following is the polar form r(cos θ + i sin θ) of the complex number z = 2√3 - 2i for θ ∈ (-π, π]?
A.4(cos(-π/6) + i sin(-π/6))
B.4(cos(π/6) + i sin(π/6))
C.2(cos(-π/6) + i sin(-π/6))
D.4(cos(-π/3) + i sin(-π/3))
Explanation: Compute r = √((2√3)^2 + (-2)^2) = √(12 + 4) = √16 = 4. The point (2√3, -2) lies in the fourth quadrant. The reference angle is α = arctan(|-2| / (2√3)) = arctan(1/√3) = π/6. In the fourth quadrant, θ = -π/6. Therefore, z = 4(cos(-π/6) + i sin(-π/6)).
4If z₁ = 2(cos(π/4) + i sin(π/4)) and z₂ = 3(cos(π/12) + i sin(π/12)), find the product z₁z₂ in rectangular form a + bi.
A.3 + 3√3 i
B.3√3 + 3i
C.6 + 6√3 i
D.3 - 3√3 i
Explanation: By the product rule for polar form, z₁z₂ = (2)(3)[cos(π/4 + π/12) + i sin(π/4 + π/12)]. Adding the angles: π/4 + π/12 = 3π/12 + π/12 = 4π/12 = π/3. Thus, z₁z₂ = 6(cos(π/3) + i sin(π/3)) = 6(1/2 + i(√3/2)) = 3 + 3√3 i.
5Using De Moivre's theorem, evaluate (1 + i)^8.
A.16
B.16i
C.-16
D.16 + 16i
Explanation: Convert 1 + i to polar form: r = √(1^2 + 1^2) = √2, θ = π/4, so 1 + i = √2(cos(π/4) + i sin(π/4)). Applying De Moivre's theorem: (1 + i)^8 = (√2)^8 [cos(8 · π/4) + i sin(8 · π/4)] = 16 [cos(2π) + i sin(2π)] = 16(1 + 0i) = 16.
6Simplify the expression (cos θ + i sin θ)^5 / (cos θ - i sin θ)^3.
A.cos(8θ) + i sin(8θ)
B.cos(2θ) + i sin(2θ)
C.cos(8θ) - i sin(8θ)
D.cos(15θ) + i sin(15θ)
Explanation: Notice that cos θ - i sin θ = cos(-θ) + i sin(-θ) = (cos θ + i sin θ)^(-1). Therefore, the denominator is ((cos θ + i sin θ)^(-1))^3 = (cos θ + i sin θ)^(-3). The quotient becomes (cos θ + i sin θ)^5 / (cos θ + i sin θ)^(-3) = (cos θ + i sin θ)^(5 - (-3)) = (cos θ + i sin θ)^8 = cos(8θ) + i sin(8θ).
7Find the square roots of the complex number 3 - 4i.
A.±(2 - i)
B.±(2 + i)
C.±(1 - 2i)
D.±(1 + 2i)
Explanation: Let (x + iy)^2 = 3 - 4i. Expanding gives x^2 - y^2 + 2xy i = 3 - 4i. Equating real and imaginary parts: x^2 - y^2 = 3 and 2xy = -4 => xy = -2. The modulus equation is x^2 + y^2 = √(3^2 + (-4)^2) = 5. Adding x^2 - y^2 = 3 and x^2 + y^2 = 5 gives 2x^2 = 8, so x^2 = 4, x = ±2. Since xy = -2, when x = 2, y = -1, and when x = -2, y = 1. Thus, the square roots are ±(2 - i).
8What is the exact value of (cos(π/6) + i sin(π/6))^6?
A.-1
B.1
C.i
D.-i
Explanation: Applying De Moivre's theorem: (cos(π/6) + i sin(π/6))^6 = cos(6 · π/6) + i sin(6 · π/6) = cos(π) + i sin(π). Since cos(π) = -1 and sin(π) = 0, the value is -1 + 0i = -1.
9In the complex Argand plane, what geometric figure is represented by the equation |z - (2 + 3i)| = 5?
A.A circle with center (2, 3) and radius 5
B.A circle with center (-2, -3) and radius 5
C.A circle with center (2, 3) and radius 25
D.A straight line perpendicular to the segment from origin to (2, 3)
Explanation: The expression |z - z₀| = r represents the locus of points z in the Argand plane whose distance from fixed point z₀ is constant and equal to r. Here, z₀ = 2 + 3i, corresponding to Cartesian coordinates (2, 3), and r = 5. Hence, it is a circle with center (2, 3) and radius 5.
10Find real numbers x and y such that (x + yi)(1 + 2i) = 7 + 4i.
A.x = 3, y = -2
B.x = 3, y = 2
C.x = -3, y = -2
D.x = 2, y = -3
Explanation: Divide 7 + 4i by 1 + 2i: x + yi = (7 + 4i)/(1 + 2i) = ((7 + 4i)(1 - 2i))/((1 + 2i)(1 - 2i)) = (7 - 14i + 4i - 8i^2)/(1 - 4i^2). With i^2 = -1, numerator = 7 - 10i + 8 = 15 - 10i, and denominator = 1 + 4 = 5. Thus, x + yi = (15 - 10i)/5 = 3 - 2i. Therefore, x = 3 and y = -2.
