Strategic Approach: Maximizing Learning with Formulas and Revision Notes

When you want to learn effectively, you can use a smart strategy by combining formulas and revision notes. These two things work together nicely. Formulas are like short explanations of important ideas. When you use them with detailed revision notes, you get a complete way to learn. Revision notes give you a strong base, and formulas help you understand better and solve problems. This mix makes hard things easier and helps you remember better. By using this strategy, you can improve how well you understand and do well in your studies.


Most Important Formulas of Sets, Relations and Functions for JEE Main

Sets:

  1. Union of Sets:

$A \cup B = \{x: x \in A \text{ or } x \in B\}$


  1. Intersection of Sets:

$A \cap B = \{x: x \in A \text{ and } x \in B\}$


  1. Complement of a Set:

$A' = \{x: x \notin A\}$


  1. Set Difference:

$A - B = \{x: x \in A \text{ and } x \notin B\}$


  1. Cartesian Product:

$A \times B = \{(a, b): a \in A, b \in B\}$


Relations:

  1. Cartesian Product of Sets A and B:

$A \times B$


  1. Domain of a Relation R:

$\text{dom}(R) = \{x : (x, y) \in R \text{ for some } y\}$


  1. Range of a Relation R:

$\text{ran}(R) = \{y : (x, y) \in R \text{ for some } x\}$


  1. Identity Relation:

$I_A = \{(a, a): a \in A\}$


  1. Inverse of a Relation R:

$R^{-1} = \{(b, a): (a, b) \in R\}$


Functions:

  1. Function Definition:

$f: A \to B$


  1. Injective (One-to-One) Function:

$f(x_1) = f(x_2) \implies x_1 = x_2$


  1. Surjective (Onto) Function:

$\text{ran}(f) = B$


  1. Bijective Function:

A function that is both injective and surjective.

  • Failing to specify the domain and codomain when defining a function or relation.

  • Confusing the concepts of injective (one-to-one) and surjective (onto) functions.

  • Assuming that every function has an inverse, without considering conditions like subjectiveness.

  • Using values outside the domain when evaluating functions or relations.

  • Misrepresenting relationships between sets using Venn diagrams.

  • Not using correct symbols (e.g., ∪, ∩, ⊆, etc.) when working with sets.

  • Forgetting to check whether a relation is reflexive or symmetric when required.
