Class 11

Best schools for admission to Class 11th Commerce stream are Delhi Public School, Allenhouse Public School, and Indus Valley Public School.

The Sequences and Series in Class 11 Maths typically carries a weightage of 6 to 8 marks out of the total 80 marks in the theory paper of mathematics. Various type of questions are asked from this chapter including MCQs, Very short answer, short and long answer type questions.  Students can use NCERT Solutions for Sequence and Series for better preparation of the exams.

The Sequences and Series is introduced as Chapter 8 in Class 11 Maths. A sequence is defined as an ordered list of numbers following a specific pattern or rule, while a series is defined as the sum of the terms of a sequence. there are several key topics discussed in this chapter;

• Arithmetic Progression (AP): Arithmetic prograssion is a sequence in which a constant term is either added or substracted in consecutive term. Constant term is called common difference.

• Geometric Progression (GP): Geometric Progression is a sequence where each term is multiplied by a constant ratio.

Doppler Effect in class 11 chapter 14 waves refers to the variation in the wavelength or frequency of a wave in relation to an observer moving relative to the wave source. When the wave source moves toward the observer, the frequency increases, and waves are compressed. If the source moves away, the frequency reduces and the waves are stretched. The Doppler Effect can be observed with the sound of a passing train or ambulance. This concept is also used in medical imaging technologies like Doppler ultrasound, radar, and astronomy to find whether galaxies or stars are moving away or towards the Earth.

The Binomial Theorem is taught as chapter 7 in Class 11 Maths as per the latest CBSE syllabus. The Binomial Theorem is a method of expanding expressions raised to a power, such as $(a + b)^n$, where n is a natural number. There are several other topics which are essential part of Binomial Theorem such as mid term, nth term, and numerical constant of nth term, which are important to understand Binomial Theorem. Binomial Theorem helps simplify complex algebraic expansions using binomial coefficients and Pascal's Triangle.

The NCERT Solutions for Permutations and Combinations include step-by-step solutions of all the exercises of the chapter. However, NCERT Solved examples are not included in the NCERT Solutions. Students can read the NCERT textbooks for the solved examples of the chapter and NCERT Solutions for the exercises. We have provided Permutations and Combination Solutions which are useful in getting clarity of concepts, learning problem-solving.

Shiksha has prepared NCERT Textbooks solutions for all the chapters of 10+2 Science stream subjects. These NCERT Solutions for Chapter 6 Permutations and Combinations  offer detailed, step-by-step explanations for all the exercises in the Permutations and Combinations.

NCERT Solutions can be used as a good mathematical guide and tool for students preparing for scholl level or competitve exams such as JEE, NDA and others. These Solutions help students understand the logic behind arrangement and selection, making complex concepts simpler and easier to grasp.

Class 11 Mathematics exam will be based on the CBSE exam format aligned with CBSE syllabus. NCERT textbooks are best resources to understand, practice and apply concepts to perform well in the annual or other school level exams. So NCERT Solutions are best mathematics guide available to understand the NCERT textbook questions in detail with explainations. For class 11 Maths preparations, NCERT Solutions for permutations and combinations are enough and those who are preparing fopr competitive exams must use some additional reference books.
