P3.4.2 - Differentiation

Differentiation using the product Differentiation of cosec x, cot x and sec x are required. rule, the quotient rule and the chain Skill will be expected in the differentiation of functions rule. generated from standard functions using products, quotients and composition, such as e3x 2x4 sin x,, cos x2 and tan2 2x. x.

Use differentiation to connect the rule to the data and decision in the question.

This matters because differentiation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply differentiation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Differentiation is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
