Iteration exam questions for GCSE maths, with worked solutions
Practise iteration with exam questions written the way GCSE Higher papers test them: using an iterative formula to approximate a solution, showing that a root lies between two values, and rearranging an equation into an iterative form. Every question comes with a worked solution and an answer, and Remix gives you a fresh version with new numbers whenever you want another go.
23 questions: 23 Higher. Every question has a worked solution and an answer. Type your answers in and the page marks them as you go.
