About this resource
Develop fluency by connecting algebraic expressions with graphs and numerical examples. This open textbook covers a broad sequence of algebra and trigonometry, with material that can support extension as well as revision. Work through a selected section actively: explain why each transformation is valid and check a result by substitution. The curriculum sequence is not a UK exam-board mapping; choose the parts that match your current learning goals.
