Differential Equations | 25 Worked Examples | Edexcel A-Level Maths

25 progressive Edexcel A-Level (9MA0) differential equations questions with full mark-scheme style worked solutions.

What’s inside:
• Easy — separating variables, integrating both sides, finding the general solution and combining constants into a single +C
• Standard — applying boundary conditions to fix the constant, solving explicitly for y, exponential growth and decay models
• Challenging — Newton’s law of cooling, rate-of-change modelling problems, interpreting and forming differential equations from worded contexts

Every solution shows every step, with M1 (method), A1 (accuracy) and B1 (independent) marks annotated at exactly the point each would be awarded. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 13 students sitting Edexcel A-Level Mathematics (9MA0) Paper 1 / Paper 2 Pure, plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
