- The vector sum of the three sides of a triangle taken in order is 0.
- The vector sum of two coinitial vectors is given by the diagonal of the parallelogram whose adjacent sides are the given vectors.
- The multiplication of a given vector by a scalar λ, changes the magnitude of the vector by the multiple |λ|, and keeps the direction same (or makes it opposite) according to as the value of λ is positive (or negative).
Chapter 11 Three Dimensional Geometry
In Chapter 11, you will find the vectors to calculate the distance between lines, a point and a line, and a line and a plane, along with the angles between them. It also introduces the concept of direction cosines
The main features of this chapter are as follows:
- Direction cosines of a line are the cosines of the angles made by the line with the positive directions of the coordinate axes.
- If l, m, n are the direction cosines of a line, then l^{2} + m^{2} + n^{2} = 1
- Direction ratios of a line are the numbers which are proportional to the direction cosines of a line.
- Skew lines are lines in space which are neither parallel nor intersecting. They lie in different planes.
- The angle between skew lines is the angle between two intersecting lines drawn from any point (preferably through the origin) parallel to each of the skew lines.
- If l_{1}, m_{1}, n_{1} and l_{2}, m_{2}, n_{2} are the direction cosines of two lines; and θ is the acute angle between the two lines; then cosθ = |l_{1}l_{2} + m_{1}m_{2} + n_{1}n_{2}|
Chapter 12 Linear Programming
This chapter explores the concept of linear programming problems and their solutions using a graphical method only.
The main features of this chapter are as follows:

- Handing cases where the region is not feasible or unbounded.
- In the previous topic, the equation is already given to us. But, we also need to create the equations and then solve. We cover different types of problems like Diet, Manufacturing, Transport and Other Problems. In these questions, we first make the equations and then find the minimum or maximum value of Z.
Chapter 13 Maths Probability
This is the last chapter of CBSE Class 12 Mathematics. Here you will learn the concept of Conditional Probability and the encounters of the same in our daily lives. This explores Bayes’ Theorem, the multiplication rule, and the independence of events. This chapter is best understood by practising as many questions as possible.
The main features of this chapter are as follows:
- 0 ≤ P (E|F) ≤ 1, P (E′|F) = 1 – P (E|F)P ((E ∪ F)|G) = P (E|G) + P (F|G) – P ((E ∩ F)|G)
- P (E ∩ F) = P (E) P (F|E), P (E) ≠ 0P (E ∩ F) = P (F) P (E|F), P (F) ≠ 0
- If E and F are independent, thenP (E ∩ F) = P (E) P (F)P (E|F) = P (E), P (F) ≠ 0P (F|E) = P (F), P(E) ≠ 0
- Theorem of total probability
- Bayes’ theorem
- A random variable is a real valued function whose domain is the sample space of a random experiment.
- Var (X) = E (X^{2}) – [E(X)]^{2}
- Trials of a random experiment are called Bernoulli trials, if they satisfy the
- following conditions :
- There should be a finite number of trials.
- The trials should be independent.
- Each trial has exactly two outcomes : success or failure.
- The probability of success remains the same in each trial.
