You will not find official solutions from Cambridge Assessment for pre-1990 papers. However, the following resources provide highly reliable reconstructions:
A classic example found in the solutions involves investigating the behavior of functions defined by integrals where the limits are variables. These solutions demonstrate the elegant use of the Fundamental Theorem of Calculus and the Chain Rule in ways that surprise students accustomed to standard differentiation questions.
