# Trigonometry

This chapter on Trigonometry has totally five sections. The aim of section one is to briefly recapitulate the fundamentals of trigonometry.Various conditional identities are dealt in the second section which are very useful to solve mathematical problems. The properties such as Sine Rule, Cosine rule and solutions of triangles are discussed in detail in the third section. The fourth section is concerned with Inverse Trigonometry where concepts such as Addition Properties, Multi-Angle Relations, Interconversions between inverse trigonometric ratios are dealt in detail. The aim of section five is to cover examples on how trigonometric equations are solved. At the end of this section, we have a series of exercises to test your understanding of this chapter,solved examples, previous years’ IIT JEE questions pertaining to this chapter.

In addition to preparing for the JEE mains and advanced exams, Cuemath Founder Manan Khurma's study material is helpful for students who are appearing for CBSE, ICSE and other State board exams.
