TopicProduct & Quotient Rules
TypeFind derivative of composite quotient/product
DifficultyModerate -0.3 This question tests standard differentiation techniques (product rule and quotient rule) with straightforward algebraic expressions. Both parts are routine textbook exercises requiring direct application of rules with minimal algebraic manipulation, making it slightly easier than the average A-level question which typically involves more steps or conceptual depth.

  1. Differentiate \(x^2(x + 1)^6\) with respect to \(x\). [3]
  2. Find the gradient of the curve \(y = \frac{x^2 + 3}{x^2 - 3}\) at the point where \(x = 1\). [3]
