# NCERT Notes for Class 11 Mathematics: Points to Remember

To help students prepare for their exams, we have provided some important points that are covered in NCERT 11th Maths which students can refer to below:

A sentence or description which can be judged to be true or false is called a statement. Statements involving mathematical relations are called mathematical statements.

The proposition or statement P(n) can be proved by the principle of mathematical induction for n ∈ N as discussed in the following three steps:

The first step is also termed as the basic step of induction in which we prove that the proposition P(n) is true for the smallest positive integer or the first natural number i.e, for n = 1. This is also called the verification step.

The next step is the induction step in which the proposition is assumed to be true for some n = k ≥ 1 i.e, we assume P(k) to be true.

An experiment whose outcomes cannot be predicted or determined in advance is called a random experiment.

Each outcome of a random experiment is known as an elementary event.

Projection Rule:

a = b cosC + c cosB

b = c cosA + a cosC

c = a cosB + b cosA

Dispersion means scattered ness around the central value.

Range is the difference between the greatest and the least values of the variable.

Range = Xmax − Xmin
