About the Book
This book is for those studying Cambridge IGCSE (International General Certificate of Secondary Education) Mathematics.
This book is written from a concept-based approach.Simple ideas are introduced at the beginning.
Students who struggle with misconceptions must be addressed and proofs such as identities are absolutely necessary.
Most books do not proof how the sine and cosine law came about. However, I think this is absolutely necessary.
This book has a very rich resource of zoomable diagrams on small devices like phone. The views are circular, sinusoidal and quadrantal.I hope to link all these three perspectives for better understanding.
