The 12th-grade Non-Medical stream focuses on physics, chemistry, and mathematics, along with optional subjects like computer science or physical education. These subjects are crucial for careers in engineering, technology, and applied sciences. Below are the basic concepts covered in this stream:

---

1. Mathematics

Mathematics is central to problem-solving and analytical thinking in the Non-Medical stream.

Key Concepts:

1. Calculus:

   • Limits, continuity, and differentiability.
   • Differentiation and its applications (rate of change, maxima/minima).
   • Integration and its applications (area under curves, volume of solids).

2. Algebra:

   • Matrices and determinants.
   • Solving linear equations and matrix transformations.

3. Vectors and 3D Geometry:

   • Dot and cross product of vectors.
   • Equations of lines and planes in space.

4. Probability and Statistics:

   • Probability distributions (binomial, Poisson, normal).
   • Mean, variance, and standard deviation.

5. Relations and Functions:

   • Types of functions (one-to-one, onto, inverse).
   • Composition of functions.

6. Differential Equations:

   • Formation and solution of first-order differential equations.
