Mathematics – Grade 12 (Matric)

Introduction to Mathematics – Grade 12 (Matric)

Mathematics in Grade 12 is an essential subject that builds upon the foundational knowledge from previous years. It prepares students for university studies, technical careers, and everyday problem-solving. The subject is divided into key areas, each requiring analytical thinking and problem-solving skills.

Key Topics in Grade 12 Mathematics

1. Algebra and Equations

   • Solving quadratic, cubic, and simultaneous equations
   • Inequalities and their graphical representations
   • Exponential and logarithmic functions

2. Functions and Graphs

   • Understanding different types of functions (linear, quadratic, exponential, logarithmic, and trigonometric)
   • Transformations and inverses of functions
   • Sketching and interpreting graphs

3. Trigonometry

   • Identities and reduction formulas
   • General solutions of trigonometric equations
   • Applications of sine, cosine, and area rules

4. Calculus

   • Differentiation: first and second derivatives, applications in motion and optimization
   • Integration: basic rules, area under a curve, and applications

5. Analytical Geometry

   • The equation of a straight line
   • Circles and parabolas in Cartesian coordinates
   • Distance, midpoint, and gradient formulas

6. Statistics and Probability

   • Data representation (mean, median, mode, standard deviation)
   • Probability rules, counting principles, and distributions

7. Financial Mathematics

   • Simple and compound interest
   • Present and future value calculations
   • Depreciation and annuities

8. Sequences and Series

   • Arithmetic and geometric sequences
   • Summation of series
   • Infinite geometric series and sigma notation
