1What is the derivative f'(x) of the function f(x) = (3x^2 - 5x + 2) e^(2x)?

A.(6x^2 - 4x - 1) e^(2x)

B.(6x - 5) e^(2x)

C.(6x^2 - 10x + 4) e^(2x)

D.(3x^2 + x - 3) e^(2x)

Explanation: Using the product rule (u·v)' = u'v + uv' with u(x) = 3x^2 - 5x + 2 and v(x) = e^(2x): u'(x) = 6x - 5 and v'(x) = 2e^(2x). Therefore, f'(x) = (6x - 5)e^(2x) + (3x^2 - 5x + 2)(2e^(2x)) = e^(2x)[(6x - 5) + (6x^2 - 10x + 4)] = (6x^2 - 4x - 1)e^(2x).

2Using integration by parts, what is the exact value of the definite integral I = ∫[0 to 1] x e^(-x) dx?

A.1 - 1/e

B.1 - 2/e

C.2/e

D.1 + 1/e

Explanation: Let u = x and dv = e^(-x) dx, so du = dx and v = -e^(-x). Applying integration by parts: ∫ x e^(-x) dx = [-x e^(-x)]_0^1 - ∫_0^1 (-e^(-x)) dx = -e^(-1) - [e^(-x)]_0^1 = -1/e - (e^(-1) - e^0) = -1/e - 1/e + 1 = 1 - 2/e.

3What is the value of the limit L = lim(x -> 0) [ln(1 + 3x) / sin(2x)]?

A.2/3

B.1

C.3/2

D.0

Explanation: As x -> 0, standard equivalents give ln(1 + 3x) ~ 3x and sin(2x) ~ 2x. Alternatively, by L'Hôpital's rule: lim(x -> 0) [ (3/(1 + 3x)) / (2 cos(2x)) ] = (3/1) / (2·1) = 3/2.

4What are the modulus and principal argument of the complex number z = -2 + 2i√3?

A.|z| = 4, arg(z) = π/3 rad

B.|z| = 2√3, arg(z) = 5π/6 rad

C.|z| = 4, arg(z) = -2π/3 rad

D.|z| = 4, arg(z) = 2π/3 rad

Explanation: The modulus is |z| = √((-2)^2 + (2√3)^2) = √(4 + 12) = √16 = 4. Factoring 4: z = 4(-1/2 + i√3/2). Since cos(θ) = -1/2 and sin(θ) = √3/2, the principal argument in the second quadrant is θ = 2π/3 rad.

5What are the solutions to the quadratic equation z^2 - (2√3)z + 4 = 0 in the set of complex numbers C?

A.z1 = 2 e^(iπ/6) and z2 = 2 e^(-iπ/6)

B.z1 = 4 e^(iπ/3) and z2 = 4 e^(-iπ/3)

C.z1 = 2 e^(iπ/3) and z2 = 2 e^(-iπ/3)

D.z1 = √3 e^(iπ/6) and z2 = √3 e^(-iπ/6)

Explanation: The discriminant is Δ = (-2√3)^2 - 4(1)(4) = 12 - 16 = -4 = (2i)^2. Thus, z = (2√3 ± 2i)/2 = √3 ± i. The modulus is r = √(3 + 1) = 2. Since √3 + i = 2(√3/2 + i/2) = 2 e^(iπ/6), the two conjugate solutions are z1 = 2 e^(iπ/6) and z2 = 2 e^(-iπ/6).

6In the complex plane, a direct plane similitude S is defined by the complex expression z' = (1 + i√3)z + 2. What are its scaling ratio k, rotation angle θ, and center invariant point Ω?

A.k = √3, θ = π/6 rad, Ω has affix ω = 1 + i√3

B.k = 2, θ = π/3 rad, Ω has affix ω = i(2√3/3)

C.k = 2, θ = -π/3 rad, Ω has affix ω = 2 - 2i

D.k = 4, θ = π/3 rad, Ω has affix ω = 2i

Explanation: For S(z) = a·z + b with a = 1 + i√3 and b = 2: ratio k = |a| = √(1 + 3) = 2. Rotation angle θ = arg(a) = π/3 rad. The invariant center point Ω satisfies ω = a·ω + b <=> ω(1 - a) = b <=> ω(1 - 1 - i√3) = 2 <=> -i√3·ω = 2 <=> ω = 2 / (-i√3) = 2i / √3 = i(2√3/3).

7What is the unique solution to the first-order differential equation y' + 2y = 4e^(-2x) satisfying the initial condition y(0) = 3?

A.y(x) = (2x + 3) e^(-2x)

B.y(x) = 4x e^(-2x) + 3 e^(2x)

C.y(x) = (4x + 3) e^(-2x)

D.y(x) = 3 e^(-2x) + 4

Explanation: The integrating factor is e^(∫ 2 dx) = e^(2x). Multiplying both sides gives (y e^(2x))' = 4. Integrating yields y e^(2x) = 4x + C, so y(x) = (4x + C)e^(-2x). Applying y(0) = 3 gives C = 3. Thus, y(x) = (4x + 3)e^(-2x).

8What is the solution to the second-order differential equation y'' + 4y' + 13y = 0 subject to initial conditions y(0) = 1 and y'(0) = -2?

A.y(x) = e^(-2x) (cos(3x) + sin(3x))

B.y(x) = e^(2x) cos(3x)

C.y(x) = e^(-2x) sin(3x)

D.y(x) = e^(-2x) cos(3x)

Explanation: The characteristic equation is r^2 + 4r + 13 = 0, which has roots r = (-4 ± √(16 - 52))/2 = (-4 ± 6i)/2 = -2 ± 3i. The general solution is y(x) = e^(-2x)[A cos(3x) + B sin(3x)]. Condition y(0) = 1 gives A = 1. The derivative is y'(x) = -2e^(-2x)[cos(3x) + B sin(3x)] + e^(-2x)[-3 sin(3x) + 3B cos(3x)]. At x = 0: y'(0) = -2(1) + 3B = -2 => 3B = 0 => B = 0. Therefore, y(x) = e^(-2x) cos(3x).

9An undamped mechanical oscillator is modeled by y''(t) + ω0^2 y(t) = F0 cos(ω t). What happens to the particular solution when the excitation pulsation ω equals the natural pulsation ω0 (resonance)?

A.The particular solution has an amplitude that grows proportionally with time t: y_p(t) = (F0 / (2ω0)) t sin(ω0 t)

B.The response remains bounded with constant amplitude Y = F0 / (ω0^2 - ω^2)

C.The system immediately decays exponentially to zero

D.The system undergoes frequency doubling with y_p(t) = F0 cos(2ω0 t)

Explanation: When ω = ω0, the driving force is in resonance with the natural frequency of the undamped system. The standard trial solution fails because ±iω0 are roots of the characteristic equation. Multiplying by t yields the secular resonant response y_p(t) = (F0 / (2ω0)) t sin(ω0 t), whose amplitude increases linearly without bound.

10What is the determinant of the 3x3 matrix A = [[2, 1, 0], [3, -1, 4], [1, 2, -1]]?

A.7

B.-7

C.-14

D.0

Explanation: Expanding along the first row: det(A) = 2 · det([[-1, 4], [2, -1]]) - 1 · det([[3, 4], [1, -1]]) + 0 = 2 · ((-1)(-1) - (4)(2)) - 1 · ((3)(-1) - (4)(1)) = 2 · (1 - 8) - 1 · (-3 - 4) = 2(-7) - 1(-7) = -14 + 7 = -7.
