All 18 chapters
- Part 1 Chapter 1: Sets and Relations
A set is a well-defined collection of objects. The chapter covers ways of writing sets, intervals on the real line, types of sets, operations such as... - Part 1 Chapter 2: Functions
A function is a special relation that gives every element of the domain exactly one image. The chapter covers domain, co-domain and range, one-one... - Part 1 Chapter 3: Complex Numbers
Equations such as x² + 1 = 0 have no real solution, so the number i = √−1 is introduced. The chapter covers imaginary and complex numbers, their... - Part 1 Chapter 4: Sequences and Series
A sequence is a list of numbers in a definite order. After recalling the arithmetic progression, the chapter studies the geometric progression... - Part 1 Chapter 5: Locus and Straight Line
A locus is a set of points satisfying a geometric condition. The chapter finds equations of loci, defines the inclination and slope of a line, gives... - Part 1 Chapter 6: Determinants
A determinant is a number attached to a square arrangement of numbers. The chapter expands determinants of order 2 and 3, studies minors, cofactors... - Part 1 Chapter 7: Limits
The limit of a function describes the value f(x) approaches as x approaches a point. It is the foundation of calculus. The chapter defines limits... - Part 1 Chapter 8: Continuity
A function is continuous if its graph has no break, jump or gap. The chapter defines continuity at a point using limits, continuity from the left and... - Part 1 Chapter 9: Differentiation
Differentiation measures the rate of change of a function. The chapter defines the derivative as a limit, finds derivatives from first principles... - Part 2 Chapter 1: Partition Values
Partition values divide an arranged set of observations into equal parts. The chapter computes quartiles, deciles and percentiles for raw data... - Part 2 Chapter 2: Measures of Dispersion
Averages alone do not show how spread out the data are. Dispersion measures the scatter of observations around a central value. The chapter covers... - Part 2 Chapter 3: Skewness
Skewness describes the lack of symmetry in a distribution. The chapter compares the positions of mean, median and mode in symmetric and skewed... - Part 2 Chapter 4: Bivariate Frequency Distribution
When two variables are recorded for each unit, the data are bivariate. The chapter classifies and tabulates bivariate data, finds marginal and... - Part 2 Chapter 5: Correlation
Correlation studies whether two variables move together. The chapter explains positive, negative and zero correlation, draws scatter diagrams... - Part 2 Chapter 6: Permutations and Combinations
Counting techniques let us count arrangements and selections without listing them. The chapter covers the fundamental principles of counting, the... - Part 2 Chapter 7: Probability
Probability measures the chance of an event on a scale from 0 to 1. The chapter defines random experiments, sample spaces and types of events, the... - Part 2 Chapter 8: Linear Inequations
An inequation compares two expressions using <, >, ≤ or ≥. The chapter solves linear inequations in one variable and shows solutions on the number... - Part 2 Chapter 9: Commercial Mathematics
Commercial mathematics applies arithmetic to business situations. The chapter covers percentages, profit and loss, simple and compound interest...
