As we all know students can’t study complete book when only 1 or 2 months are left before JEE Examination. At that time all students want to cover maximum topics in each subject. Students can achieve this if they focused only on important concepts and formulae.

After observing the pattern and difficulty level of the questions asked in previous year papers of JEE Examination, our Subject Experts of Mathematics have prepared chapter notes of chapter Trigonometric Functions. About 2-3 questions are always asked from this topic in JEE Examination.

In these chapter notes, they have included all important topics of chapter Trigonometric Functions like definition of angle, relation between degree and radian, trigonometric identities (reciprocal, quotient, even/odd, Pythagorean, co-function etc), law of sines, law of cosines, formula of area of triangles etc.
