Chapters of NCERT Solutions for Class 12 Maths

Chapter-1: Relations and Functions

  3. Exercise-1.3
  4. Exercise-1.4&
  5. Miscellanious Exercise chapter-1
  1. A mapping f : X → Y is said to be a function if each element in the set X has it’s image in set Y. It is possible that a few elements in the set Y are present, which are not the images of any element in set X.
  2. Every element in set X should have one and only one image. That means it is impossible to have more than one image for a specific element in set X. Functions can’t be multi-valued
    (A mapping that is multi-valued is called a relation from X to Y).
  3. Set ‘X’ is called domain of the function ‘f’. Set ‘Y’ is called the co-domain of the function ‘f’.
  4. Set of images of different elements of set X is called the range of the function ‘f’.
  5. The function ‘h’ defined above is called the composition of f and g and is denoted by gof.
  6. If f : X→Y be a function defined by y = f(x) such that f is both one-one and onto, then there exists a uniquefunction g : Y→X such that for each y→Y, g(y) = x if and only if y = f(x). The function g so defined is called the inverse of f and denoted by f -1. Also if g is the inverse of f, then f is the inverse of g and the two functions f and g are said to be inverses of each other. The condition for existence of inverse of a function is that the function must be one-one and onto.
  7. f(x) - f(-x) = 0 even function
  8. f(x) + f(-x) = 0 odd function

  5. Miscellanious Exercise chapter-3

A set of mn numbers (real or complex) arranged in the form of a rectangular array having 'm' rows & 'n' columns is called an m  n matrix. [to be read as m by n matrix].The numbers a11, a12… etc are called elements of the matrix. The element aij belongs to ith row and jthcolumn.

  • (i)Square Matrix An m n matrix for which m = n(i.e. the number of rows is equal to the number of columns) is called a square matrix of order n. The element aijof a square matrix
  • A = [aij]n*nfor which i = j i.e., the elements a11, a22,…,annare called the diagonal elements.
  • (ii)Null Matrix or Zero Matrix
  • The m -n matrix whose all elements are zero is called a null matrix of order m - n. It is usually denoted by O.
  • (iii)Unit Matrix or Identity Matrix
  • A square matrix each of whose principal diagonal element is '1' and each of whose nondiagonal element is equal to zero is called a unit matrix or an identity matrix and is denoted by I. In will denote a unit matrix of order n

Chapter-4: Determinants

  2. Exercise-4.2
  3. Exercise-4.3
  4. Exercise-4.4
  5. Exercise-4.5
  6. Exercise-4.6
  7. Miscellanious Exercise chapter-4

Important properties of Determinants

  1. If rows be changed into columns and columns into the rows, the determinant remains unaltered.
  2. If any two row (or columns) of a determinant are interchanged, the resulting determinant is the negative of the original determinant.
  3. If two rows (or two columns) in a determinant have corresponding entries that are equal (or proportional), the value of determinant is equal to zero.
  4. If each of the entries of one row (or columns) of a determinant is multiplied by a nonzero constant k, then the determinant gets multiplied by k.
  5. If each entry in a row (or column) of a determinant is written as the sum of two or more terms then the determinant can be written as the sum of two or more determinants.
  6. If to each element of a line (row or column) of a determinant be added the equi-multiples of the corresponding elements of one or more parallel lines, the determinant remains unaltered
  7. If each entry in any row (or any column) of determinant is zero, then the value of determinant is equal to zero.
  8. If a determinant D vanishes for x = a, then (x-a) is a factor of D, In other words, if two rows (or two columns) become identical for x = a. then (x- a) is a factor of D.
  9. If in a determinant (of order three or more) the elements in all the rows (columns) are in A.P. with same or different common difference, the value of the determinant is zero.

In this section we examine some applications in which derivatives are used to represent and interpret the rates at which things change in the world around us. LetSbe the displacement described by a particle over the time intervalt. ThenSwill be a function oft, we write asS=f(t).

The velocity is the derivative of the position functionS=f(t) with respect to time. At timetthe velocity is ds/dt. Acceleration is the derivative of velocity with respect to time. If a body's position at timetisS=f(t), the body's acceleration at timetis a(t)=dv/dt
