Detailed Breakdown of the Maths Formula Book
Algebra, a key part of many competitive exam syllabi, is a fundamental branch of mathematics. Aditya Ranjan’s formula book thoroughly explores various algebraic concepts.
- Basic Algebraic Identities: This book covers important algebraic identities like (𝑎+𝑏)^2, (a-b)^2, and (a+b)(a−b). These identities are essential f or solving equations quickly and performing complex algebraic manipulations.
- Quadratic Equations: The section on quadratic equations details the standard form 𝑎𝑥^2+𝑏𝑥+𝑐=0 and various methods to solve these equations, such as factoring, completing the square, and using the quadratic formula.
- Progressions: Arithmetic and geometric progressions are extensively covered with formulas for the n-th term and the sum of n terms. These progressions are commonly tested in competitive exams, making this section indispensable.
Geometry is an important topic in competitive exams. Aditya Ranjan's formula book covers both basic and advanced geometric principles.
- Triangles: The book covers the properties of different types of triangles, such as equilateral, isosceles, and scalene. It also explains the corresponding formulas for area and perimeter. Additionally, important theorems like Pythagoras' theorem and the properties of similar triangles are included.
- Circles: The book contains formulas about circles, such as how to find the area and circumference. It also covers the properties of chords and tangents. These formulas are useful for solving complex geometric problems.
- Polygons: We provide detailed formulas for regular polygons, including how to calculate the sum of the interior angles, which is (𝑛−2) × 180∘, and the measure of each interior angle for regular polygons. Additionally, we discuss the properties of special polygons such as squares, rectangles, and parallelograms.
Trigonometry is important for competitive exams, and Aditya Ranjan’s book makes it easier to understand with simple formulas.
- Basic Trigonometric Ratios: The book starts with the basic trigonometric ratios (sine, cosine, and tangent) and their relationships in right-angled triangles. It also covers reciprocal ratios (cosecant, secant, and cotangent).
- Trigonometric Identities: The following identities are thoroughly explained with examples:- sin^2𝜃+cos^2𝜃=1, 1+tan^2𝜃=sec^2𝜃, 1+tan^2θ=secθ.
- Applications: The book shows how trigonometry can be used to solve problems about heights and distances, which are often found in competitive exams.
For students aiming for high scores in exams like JEE and other engineering entrance tests, understanding calculus is essential.
- Limits and Continuity: The book introduces the concept of limits with basic formulas and techniques for evaluating them. It also covers the idea of continuity and discontinuity in functions.
- Differentiation: Aditya Ranjan explains the basics of differentiation which includes the power rule, product rule, quotient rule, and chain rule. The practical uses of differentiation, such as finding the slope of a curve and solving optimization problems, are also covered.
- Differentiation: The book presents basic integration techniques, including indefinite and definite integrals, and standard formulas. It also covers using integration to calculate areas under curves and solve problems involving motion.
