Permutation & Combination Class XI Chapter 6 Explanation of Formulas and basic points related to the permutation and combination class XI chapter 6, method of arrangement and selection of the objects. Fundamental Principal of Counting :   If an event can occur in m different ways, following which another event can occur in n different ways, then the total number of occurrence of the events in the given order is   m x n.

Class XII : Chapter : 4 : Determinants Formulas and basic concepts based on the determinants chapter 4 class XII, properties of determinants, method of finding the solutions of linear equations by matrix method. Determinant:   To every square matrix A =  [a ij ]  of order n, we can associate a number (real or complex) called determinant of the square matrix  A.  Determinant of matrix [A] is denoted by |A| Determinants is a number associated with the square matrix. For Example:   Let a matrix A of order 2 x 2 is given by       then  Let a matrix of order  3 x 3 is given by :  Determinant of matrix A is denoted by |A| and is given by  Expand it along the first row     |A| = 3(25 - 4) - 4(- 10 + 12) + 5(2 - 15) |A| = 3 × 21 - 4 × 2 + 5 × - 13 |A| = 63 - 8 - 65 = -10  Note: 1. For matrix A, |A| is read as determinant of A and not modulus of A. 2. Only square matrix have determinant. 3. For easier calculation to find the determinants of matrix of order 2 x 2

Assignment Class X Chapter 6 : Triangle Extra questions of class x, chapter 6, extra questions of triangle chapter 6, class x Important Result :   Internal bisector of angle of a triangle divides the opposite side internally in the ratio of the sides containing the angle.    In Triangle ABC, if AD is the bisector of ∠A then \[\frac{AB}{AC}=\frac{BD}{DC}\] For detailed study and basic concepts related to the similarity of triangles: Click Here Solve the following questions Question 1: Q. 1. PA, QB and RC are each perpendicular to AC then Question 2: If the bisector of an angle of  triangle bisects the opposite side, then prove that the triangle is isosceles. Question 3: O is any point inside a triangle ABC. The bisectors of ∠AOB, ∠BOC and ∠COA meet the side AB, BC and CA in points D, E, F respectively.  Show that AD X BE X CE = BD X EC X FA Question 4: In triangle ABC, AD is the internal bisector of ∠A which meets BC
