Chapter 2 Inverse Trigonometric Functions Formulas

Students might already have some basic idea about Trigonometric from their previous classes. In Class 12, students will learn more advanced concepts of Inverse Trigonometric Functions. Practicing NCERT notes can be a great way to prepare for competitive exams. Students should go through all exercises to score higher marks.

Vidyakul provides NCERT notes for Class 12 with over 1500 questions for practice and 9 books for reference. It will play an important role in helping the students prepare for the exams. Read further to know more.

MATHEMATICS NOTES CHAPTER-2

Points to Remember

Below we have provided some of the important points to remember for this chapter to ace the exams:

• Inverse trigonometric functions have a principal value that falls within the range of the principal value branch.

• Trigonometric functions cannot be represented with inverse trigonometric functions as reciprocals.

• The value that lies in the principal branch range is the principal value of a trigonometric function.

• A tangent function can be explained as the inverse of an arctangent function. It is denoted by tan-1x.

• The inverse of the tangent function is y = tan-1x (arctangent x). This function is a domain of -∞ < x < ∞. The range is expressed as -π / 2 < y < π /2.

Topics and Sub-topics

In this chapter, students will study the restrictions on domains and ranges of trigonometric functions that ensure the existence of their inverses and observe their behavior through graphical representations. The NCERT Class 12 Maths notes have detailed step-by-step solutions that the students can refer to. Designed by the top academic experts at Vidyakul, the Class 12 Maths Chapter 2 NCERT notes can help students prepare for the exams.

When the students are stuck while solving any problem related to the chapter, they can refer to NCERT notes. The concepts included in the Inverse Trigonometric Functions chapter are tabulated below:
