Students learn about three-dimensional coordinate systems, distance between points, and direction cosines. The chapter introduces basic concepts used to describe geometric shapes in space, important in engineering and physics.
13. Limits and Derivatives
This is an introductory chapter to calculus. It explains the concept of limits and the basics of derivatives, including their physical interpretation as rate of change. These concepts are fundamental in higher mathematics, science, and economics.
14. Mathematical Reasoning
The chapter teaches logical thinking and the structure of mathematical arguments. Students learn about statements, implications, negations, and basic logic connectives. It helps develop proof-based problem-solving and analytical skills.
15. Statistics
This chapter covers the analysis of data using measures like mean, median, mode, and standard deviation. It helps students summarize and interpret data sets. These tools are essential in economics, biology, business, and social sciences.
16. Probability
This chapter introduces the concept of chance and the likelihood of events. It explains outcomes, sample spaces, and the basic rules of probability. These ideas are important in risk analysis, predictions, and real-world decision-making.
