WAEC 2025 Mathematics Essay Sample Questions and Answers
Question 1:
A matrix A=[2134]A = \begin{bmatrix} 2 & 1\\ 3 & 4 \end{bmatrix}A=[2314].
Find the determinant of matrix AAA.
Answer:
Determinant of A=(2×4)−(1×3)=8−3=5A = (2×4) - (1×3) = 8 - 3 = 5A=(2×4)−(1×3)=8−3=5
Question 2:
Solve the equation:
∫(4x3+2x)dx\int (4x^3 + 2x)dx∫(4x3+2x)dx
Answer:
Using integration rules:
∫(4x3+2x)dx=4x44+2x22+C=x4+x2+C\int (4x^3 + 2x) dx = \frac{4x^4}{4} + \frac{2x^2}{2} + C = x^4 + x^2 + C∫(4x3+2x)dx=44x4+22x2+C=x4+x2+C
Question 3:
A particle moves in a straight line so that its displacement sss at time ttt is given by s=3t2+2ts = 3t^2 + 2ts=3t2+2t.
Find the velocity of the particle at t=2t = 2t=2.
Answer:
Velocity is the derivative of displacement:
v=dsdt=6t+2⇒v(2)=6(2)+2=14 units/sv = \frac{ds}{dt} = 6t + 2 \Rightarrow v(2) = 6(2) + 2 = 14 \text{ units/s}v=dtds=6t+2⇒v(2)=6(2)+2=14 units/s
