Relations And Functions

Definition/Theorems

1. Empty relation holds a specific relation R in X as: R = φ ⊂ X × X.
2. A Symmetric relation R in X satisfies a certain relation as: (a, b) ∈ R implies (b, a) ∈ R.
3. A Reflexive relation R in X can be given as: (a, a) ∈ R; for all ∀ a ∈ X.
4. A Transitive relation R in X can be given as: (a, b) ∈ R and (b, c) ∈ R, thereby, implying (a, c) ∈ R.
5. A Universal relation is the relation R in X can be given by R = X × X.
6. Equivalence relation R in X is a relation that shows all the reflexive, symmetric and transitive relations.

Determinants

Definition/Theorems

1. The determinant of a matrix A = [a₁₁]_{1 × 1} can be given as: |a₁₁| = a₁₁.
2. For any square matrix A, the |A| will satisfy the following properties:
   • (i) |A′| = |A|, where A′ = transpose of A.
   • (ii) If we interchange any two rows (or columns), then sign of determinant changes.
   • (iii) If any two rows or any two columns are identical or proportional, then the value of the determinant is zero.
   • (iv) If we multiply each element of a row or a column of a determinant by constant k, then the value of the determinant is multiplied by k.

Three Dimensional Geometry

Definition/Properties

1. Direction cosines of a line are the cosines of the angle made by a particular line with the positive directions on coordinate axes.
2. Skew lines are lines in space which are neither parallel nor intersecting. These lines lie in separate planes.
3. If l, m and n are the direction cosines of a line, then l² + m² + n² = 1.

Frequently Asked Questions – FAQs

What are the basic maths formulas for class 12th?

The basic formulas that are introduced for class 12th students are for the topics:
Algebra
Geometry
Matrices
Calculus
Linear Programming
Probability

How many formulas are there in Maths?

There are many formulas in Maths for which we cannot keep a record. Because for each and every concept there are formulas to find the solutions for mathematical problems. Also, for each grade the level of formulas are different.

What is the importance of Maths formulas?

The importance of learning Maths formulas is that it helps us to solve problems easily. We should have to put the values of entities in the given formula and simplify them. For example, to find the average of a given set of values, we have to need to know first the sum of all those values and number of values. Hence, the average will be equal to the ratio of the sum of values and the number of values.

What is the formula for integrating trigonometry ratio?

∫cos(a) da = Sin a + C
∫sin (a) da = -Cos a + C
∫sec^2a da = tan a + C

What is the integration for exponential function?

The value of exponential function e^x remains the same with constant even after integration.
∫e^x dx = e^x + C

Ques: How many formulas are present in the class 12 CBSE Maths?

Ans: It is almost next to impossible to keep a record of all the formulas given in the Maths book of class 12 CBSE. As for each and every theory and concept, given in the book, there exist one or more formulas to help find the solutions for the given mathematical problems. As well the level of formulas increases with each grade making class 12 Mathematics the most difficult on the school level.
