About this paper
COT 305: End of Semester Examination for COT305 Mathematics III, Department of Computer Engineering, College of Technology, University of Buea, Instructors Mbapte/Nana/Suh, 31 January 2026. Exercise 1: forming and solving a difference equation for world population growing at 1.12% annually from a 2017 base of 7.6 billion, and projecting the 2050 population. Exercise 2: finding the general solution of a 2x2 linear system of first-order ODEs; verifying two given exponential solutions of a second-order linear ODE, computing their Wronskian, deducing the general solution, and solving an initial value problem. Exercise 3: solving a forced second-order IVP via the Laplace transform.
