1. Trigonometric Functions

Trigonometry deals with relationships between angles and sides of triangles.

Key Concepts:

• Degree and radian measure
• Trigonometric ratios and identities
• Graphs of sine, cosine, and tangent functions
• General solutions of trigonometric equations

Example:

If sin⁡ x =1/2, find general solution:

x=nπ+(−1)n6π​,n∈Z

2. Measures of Dispersion

This chapter is part of statistics and helps understand how data varies.

Key Topics:

• Range
• Quartile deviation
• Mean deviation
• Standard deviation
• Coefficient of variation

Importance:

Helps in data analysis, economics, social sciences, and research.

3. Probability

Probability is the study of chance and uncertainty.

Key Concepts:

• Classical and empirical probability
• Sample space and events
• Addition and multiplication rules
• Conditional probability
• Bayes’ theorem (basic level)

Example:

If a die is thrown, what is the probability of getting an even number?

Answer: 36= 3/6=1/2

This topic is crucial for business, gaming theory, and real-world decision-making.

4. Complex Numbers

Complex numbers expand the number system beyond real numbers.

Definitions:

• Complex number: z=a+biz = a + biz=a+bi where i=−1i = \sqrt{-1}i=−1
• ​
• Conjugate: z‾=a−bi\overline{z} = a - biz=a−bi
• Modulus and argument of a complex number
• Polar and exponential form
• Operations: Addition, subtraction, multiplication, division

Application:

Used in electrical engineering, signal processing, and control systems.

5. Sequence and Series

This chapter explores ordered sets of numbers following a rule.

Types:

• Arithmetic Progression (AP)
• Geometric Progression (GP)
• Arithmetic-Geometric Series
• Formulae for nth term and sum of n terms

Mastery of sequences helps in financial mathematics and computer algorithms.

6. Straight Line

Analytical geometry focuses on the properties of lines in a plane.

Topics:

• Slope of a line
• Point-slope form
• Two-point form
• General equation of a line
• Distance from a point to a line
• Angle between lines

Importance:

Used in coordinate geometry, graphics, and architecture.

7. Conic Sections

Conic sections are curves obtained by intersecting a plane with a cone.

Includes:

• Circle
• Parabola
• Ellipse
• Hyperbola

These curves have applications in astronomy, physics, and design.

8. Limits

Limits form the foundation of calculus.

Concepts:

• Evaluating limits using algebraic techniques
• Left-hand limit (LHL) and right-hand limit (RHL)
• Limits at infinity
• Indeterminate forms and L'Hôpital’s Rule (introductory)

9. Derivatives

Differentiation is the process of finding the rate of change.

Topics Covered:

• Derivative from first principles
• Derivatives of algebraic and trigonometric functions
• Rules: Sum, product, quotient
• Chain rule
• Applications: Tangents, normals, increasing/decreasing functions

Example:

Calculus is key in physics, economics, biology, and computer science
