Differential Equations is one of the core chapters of calculus in the CBSE Class 12 Mathematics syllabus. It builds upon the concepts of derivatives and integrals and helps students understand mathematical modeling of real-life problems. CBSE frequently asks Assertion and Reason questions from this chapter to test conceptual clarity and logical reasoning.

Assertion and Reason questions consist of two statements:
Assertion (A) is a mathematical statement that may be true or false.
Reason (R) is a statement that explains or supports the assertion.
Students must choose the correct option based on the truth value and logical relationship between Assertion and Reason. These questions are designed to evaluate conceptual understanding rather than calculation skills.
Determinants play a crucial role in the CBSE Class 12 Mathematics syllabus. This chapter contributes significantly to board exam marks and also helps in understanding future topics. Assertion and Reason questions from determinants often appear in objective sections and are considered high-scoring when prepared well.
A determinant is a real number associated with a square matrix. It provides information about the nature of solutions of linear equations and the invertibility of matrices.
The order of a determinant depends on the number of rows and columns in the matrix. CBSE commonly asks questions from determinants of order 2 and 3.
Expansion of determinants using minors and cofactors is an important concept. Assertion questions often test whether students understand expansion along rows or columns.
Assertion and Reason questions consist of two statements. The Assertion is a mathematical statement that may be true or false. The Reason is a statement that explains or justifies the Assertion. Students must analyze both statements independently and then determine whether the Reason correctly explains the Assertion.
This chapter carries considerable weight in the CBSE Class 12 Mathematics board examination. Questions from differential equations appear in objective, short answer, and long answer formats. Assertion and Reason questions are commonly included and are considered scoring when concepts are clearly understood.
A differential equation is an equation involving derivatives of a dependent variable with respect to an independent variable. Assertion and Reason questions often test understanding of this basic definition.
The order of a differential equation is the order of the highest derivative present in the equation. Many Assertion and Reason questions are based on identifying the correct order.
The degree of a differential equation is the power of the highest order derivative after the equation is made free from radicals and fractions. Assertion and Reason questions often test whether students correctly identify the degree.
Formation of differential equations involves eliminating arbitrary constants from a given equation. Assertion and Reason questions may test whether the correct number of derivatives is taken.
In such equations, variables can be separated on opposite sides of the equation. Assertion and Reason questions often test whether separation of variables is applicable.
Homogeneous differential equations have a specific form where the degree of numerator and denominator is the same. These are frequently tested in conceptual questions.
Linear differential equations are of the form involving first-order derivatives and linear terms. Assertion and Reason questions often test recognition of linear form and solution method.
The solution of a differential equation is a function that satisfies the given equation. Assertion and Reason questions may test whether a given function is a solution.
The general solution contains arbitrary constants, while the particular solution is obtained by applying given conditions. Assertion and Reason questions often test the difference between these two concepts.
These questions test whether students correctly identify the order and degree of a given differential equation. The Reason usually explains the rule used.
Such questions test whether the correct method has been applied to solve a differential equation. The Reason explains why a particular method is suitable.
Students may be asked whether the formed differential equation is correct. The Reason often explains the elimination of constants.
Students often confuse order with degree. Another common mistake is incorrect separation of variables. Errors in identifying linear or homogeneous equations also lead to wrong Assertion and Reason answers.
Students should clearly understand definitions of order, degree, and types of differential equations.
Practicing Assertion and Reason questions improves speed and accuracy.
Each statement should be analyzed independently before selecting the correct option.
CBSE focuses on competency-based assessment. Assertion and Reason questions are included in the objective section and test conceptual clarity rather than lengthy calculations.
With clear understanding of concepts and standard methods, this chapter becomes highly scoring. Assertion and Reason questions are generally direct and based on definitions and properties.
