About this paper
COT 305: COT305 End-of-Semester Exam Jan 2026 (2hrs, Mbapte/Nana/Suh, Department Computer Engineering) – Exercise 1: population difference equation at 1.12% annual growth, value in 2050. Exercise 2: system ẋ₁=x₁+x₂/ẋ₂=4x₁+x₂ (eigenvalues -1,3), Wronskian of e^{2x}/e^{5x} for y''-7y'+10y=0 verified fundamental, IVP y(0)=-1,y'(0)=1 solved. Exercise 3: Laplace IVP y''+4y'=3 sin t (recalled partial-fraction identity has typo 33/170→30/170=3/17, corrected in solution), Fourier cos(x/2) on [-π,π] → sum ∑1/(4n²-1)=1/2. N.B.
