Sample Angola Military Technical Institute (ISTM) Exam Practice Questions

Try these sample questions to test your Angola Military Technical Institute (ISTM) Exam exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the derivative with respect to x of the function f(x) = x³ · e^(2x)?
A.f'(x) = 6x² · e^(2x)
B.f'(x) = x³ · e^(2x) + 3x²
C.f'(x) = x² · e^(2x) · (3 + 2x)
D.f'(x) = 3x² · e^(2x)
Explanation: Using the product rule (u · v)' = u'v + uv': u = x³ → u' = 3x²; v = e^(2x) → v' = 2e^(2x). Then f'(x) = 3x²e^(2x) + 2x³e^(2x) = x²e^(2x)(3 + 2x).
2Evaluate the definite integral: ∫ (from 0 to 2) (3x² - 4x + 1) dx.
A.8
B.2
C.0
D.4
Explanation: Antiderivative F(x) = [x³ - 2x² + x] evaluated from 0 to 2: F(2) = (2³ - 2(2²) + 2) = (8 - 8 + 2) = 2. F(0) = 0. Thus the integral equals 2 - 0 = 2.
3What is the determinant of the 3×3 matrix A = [[1, 2, 3], [0, 4, 5], [0, 0, 6]]?
A.24
B.11
C.0
D.60
Explanation: For an upper triangular matrix, the determinant is the product of its diagonal entries: det(A) = 1 × 4 × 6 = 24.
4Solve the first-order separable differential equation dy/dx = 2x · y for y > 0 with initial condition y(0) = 3.
A.y(x) = e^(x²) + 2
B.y(x) = 3 · e^(2x)
C.y(x) = 3x² + 3
D.y(x) = 3 · e^(x²)
Explanation: Separating variables: dy / y = 2x dx. Integrating both sides: ln(y) = x² + C → y = A · e^(x²). Using y(0) = 3: 3 = A · e⁰ → A = 3. Thus y(x) = 3e^(x²).
5What is the modulus |z| and argument θ of the complex number z = 1 + i√3?
A.|z| = 2 and θ = π/6 (30°)
B.|z| = √2 and θ = π/4 (45°)
C.|z| = 2 and θ = π/3 (60°)
D.|z| = 4 and θ = π/6 (30°)
Explanation: Modulus |z| = √(1² + (√3)²) = √(1 + 3) = √4 = 2. The argument is θ = arctan(√3 / 1) = 60° = π/3 radians.
6What is the equation of the ellipse centered at (0, 0) with major axis of length 10 along the x-axis and minor axis of length 6 along the y-axis?
A.x² / 10 + y² / 6 = 1
B.x² / 25 + y² / 9 = 1
C.x² / 100 + y² / 36 = 1
D.x² / 9 + y² / 25 = 1
Explanation: The semi-major axis is a = 10/2 = 5 (so a² = 25) and semi-minor axis is b = 6/2 = 3 (so b² = 9). The standard equation is x²/a² + y²/b² = 1 → x²/25 + y²/9 = 1.
7Calculate the eigenvalues of the 2×2 matrix A = [[3, 1], [0, 2]].
A.λ₁ = 3 and λ₂ = 2
B.λ₁ = 1 and λ₂ = 5
C.λ₁ = 6 and λ₂ = 0
D.λ₁ = -3 and λ₂ = -2
Explanation: For a triangular matrix, the eigenvalues are simply the entries along the main diagonal: det(A - λI) = (3 - λ)(2 - λ) - 0 = 0 → λ₁ = 3 and λ₂ = 2.
8Using L'Hôpital's rule, evaluate the limit: lim (x → 0) [ (e^(3x) - 1) / sin(2x) ].
A.1
B.0
C.3
D.3/2 (or 1.5)
Explanation: Direct substitution gives 0/0. Applying L'Hôpital's rule by differentiating numerator and denominator: lim (x → 0) [ 3e^(3x) / (2cos(2x)) ] = (3 · 1) / (2 · 1) = 3/2.
9What is the cross product u × v of vectors u = (1, 0, 0) and v = (0, 1, 0)?
A.(1, 1, 0)
B.(0, 0, 0)
C.(0, 0, 1)
D.(0, 0, -1)
Explanation: The cross product of standard unit basis vectors î × ĵ is the k̂ unit vector along the z-axis: (1, 0, 0) × (0, 1, 0) = (0, 0, 1).
10What is the general solution of the second-order homogeneous differential equation y'' + 9y = 0?
A.y(x) = C₁ · cos(3x) + C₂ · sin(3x)
B.y(x) = C₁ · e^(3x) + C₂ · e^(-3x)
C.y(x) = C₁ · cos(9x) + C₂ · sin(9x)
D.y(x) = (C₁ + C₂x) · e^(3x)
Explanation: The characteristic equation is r² + 9 = 0 → r² = -9 → r = ±3i. Complex conjugate roots r = 0 ± 3i yield sinusoidal general solutions y(x) = C₁ cos(3x) + C₂ sin(3x).
