Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores. [11]
In mathematics, the determinant is a scalar-valued function of the entries of a square matrix.The determinant of a matrix A is commonly denoted det(A), det A, or | A |.Its value characterizes some properties of the matrix and the linear map represented, on a given basis, by the matrix.
A number of other books, Ram Sharan Sharma's Ancient India, Satish Chandra's Medieval India, Bipan Chandra's Modern India and Arjun Dev's India and the World were published in 1970's. [7] [6] [8] These texts were intended to be "model" textbooks which were "modern and secular," free of communal bias and prejudice.
In vector calculus, the Jacobian matrix (/ dʒ ə ˈ k oʊ b i ə n /, [1] [2] [3] / dʒ ɪ-, j ɪ-/) of a vector-valued function of several variables is the matrix of all its first-order partial derivatives.
However, having all determinants zero does not imply that the system is indeterminate. A simple example where all determinants vanish (equal zero) but the system is still incompatible is the 3×3 system x+y+z=1, x+y+z=2, x+y+z=3.
The full domain of cases in which the product rule can be generalized is still a subject of research. However, there are some basic instances that can be stated. Given a multilinear form f ( x 1 , ..., x r ) we can apply a linear transformation on the last argument using an n × n matrix B , y r = B x r .
The determinant of a square Vandermonde matrix is called a Vandermonde polynomial or Vandermonde determinant.Its value is the polynomial = < ()which is non-zero if and only if all are distinct.
The use of Slater determinants ensures an antisymmetrized function at the outset. In the same way, the use of Slater determinants ensures conformity to the Pauli principle. Indeed, the Slater determinant vanishes if the set {} is linearly dependent. In particular, this is the case when two (or more) spin orbitals are the same.
