Chapter 03 – Trigonometric Functions

Class XI - Mathematics
Unit 1 - Sets and Functions
Chapter 3 - Trigonometry
T - Ratios and Quadrants Ex. 3.2

This Channel initiated by Dr. D. R. Vij (former Professor of Physics, Kurukshetra University, India) primarily aims at taking free education to the doorsteps of learners who for various economic and social factors can not avail benefits of regular coaching.
In view of the congested classrooms coupled with hefty tuition fee, social taboos and hazards of travelling (for girls in particular) this mode of extending education had become a necessity.

This self-learning approach is a definite step towards democratization of education i.e. taking education even to individuals who staying in remote and far off areas were being deprived of education for no fault of theirs.
