1. What is the Syllabus of NCERT Book Class 11 Maths?

The 11th Math NCERT book covers 16 chapters â€“ (1) Sets, (2) Relations and Functions, (3) Trigonometric Functions, (4) Principle of Mathematical Induction, (5) Complex Numbers and Quadratic Equations, (6)Linear Inequalities, (7) Permutations and Combinations, (8)Binomial Theorem, (9)Sequences and Series, (10)Straight Lines, (11)Conic Sections, (12)Introduction to Three Dimensional Geometry, (13) Limits and Derivatives, (14)Mathematical Reasoning, (15) Statistics, and (16) Probability.

2. What are Complex Numbers?

Ans.Â As explained in this NCERT book for Class 11 Maths, a complex number is any number which is expressed as (a+bi), where a and b amount to real numbers and the value of i is the solution of x2=-1. Since real numbers will never satisfy this equation, it is called an imaginary number. However, a complex number can be purely real if its assumption amounts to 0.

3. What are Sets?

Ans. NCERT PDF Class 11 Maths explains sets as a defined aggregate of objects which may be represented by two methods â€“ (1) Tabular or Roster form, and (2) Set-builder form. In a Roster form, all members of a set are within braces, separated by commas. Set builder form, contrarily, arranges the properties satisfied by all elements.

4. What is the Distance Between Two Parallel Straight Lines?

Ans. As elucidated in 11th NCERT Maths PDF, the distance between two parallel straight lines is a measure of the perpendicular line which crosses through two parallel lines when placed in a Cartesian plane. In other words, it is same as a perpendicular distance from one point to one of the lines.Â
