ICSE Class 11 Mathematics — Chapter Summary

Sets form the basic language of modern mathematics. A set is a well-defined collection of objects, so it is always possible to decide whether a given object belongs to it or not. Elements of a set are written with small letters, while sets are usually written with capital letters. Set theory begins

Relations and functions describe how elements of one set are connected to elements of another set. A relation is any subset of a Cartesian product, while a function is a special relation in which every element of the starting set has exactly one image. The chapter also develops Cartesian products of

Trigonometric functions are built from angles, circle geometry, and periodic motion. The chapter begins with the idea of an angle as the figure formed by two rays with a common end-point, then introduces degree and radian as the main units for measuring angles. It then develops the six trigonometric
