In this topic, we know how to use inverse functions in trigonometry to get the angle with any of the trigonometry ratios. Trigonometric Functions is very important and mostly used in the field of engineering, physics, geometry and navigation.

Inverse trigonometric functions are also known as “Arc Functions”, which produce the length of arc needed to get that particular value. Trigonometric functions are especially applicable to the right angle triangle. There are a total of six inverse trig functions including Arcsine, Arccosine, Arctangent, Arccotangent, Arcsecant, Arccosecant.

The matrix is just an arrangement of certain quantities. The elements which are used in a matrix may be real or complex numbers. When the elements of a matrix are real, then it is known as a real matrix.

**Summary:** Concept, notation, order, equality, types of matrices, zero and identity matrix, transpose of a matrix, symmetric, and skew symmetric matrices. Operation on matrices: Addition and multiplication and multiplication with a scalar. Simple properties of addition, multiplication and scalar multiplication. Noncommutativity of multiplication of matrices and existence of non-zero matrices whose product is the zero matrix (restrict to square matrices of order 2).Concept of elementary row and column operations. Invertible matrices and proof of the uniqueness of inverse, if it exists; (Here all matrices will have real entries).

### 4. Determinants

Here in this chapter, NCERT Solutions for Class 12 Maths Chapter 4 Determinants, we learn Introduction to Determinants.
