Description:

This test consist of 10 questions.Students should ideally take 10 minutes to complete the test. This test is useful for those students who are preparing for IIT JEE, AIEEE or any other engineering entrance test. This test consist of questions from Trigonometry and which, in general, is focused in AIEEE and IIT JEE. In this chapter, Trigonometric Equations and Inverse Trigonometric Functions are key topic and mostly application based questions are asked.
