    Study Notes

    Introduction to Calculus

    • Calculus is a branch of mathematics that deals with continuous change.
    • It comprises two major branches: differential calculus and integral calculus.
    • Differential calculus focuses on rates of change, slopes of curves, and tangents.
    • Integral calculus focuses on accumulating quantities, areas under curves, and volumes.

    Differential Calculus

    • Concept of Limits:
      • The foundation of differential calculus is the concept of a limit.
      • A limit describes the behavior of a function as its input approaches a particular value.
      • Understanding limits is crucial for defining derivatives and continuity.
    • Derivatives:
      • The derivative of a function at a point represents the instantaneous rate of change of the function at that point.
      • It measures the slope of the tangent line to the graph of the function at that point.
      • The derivative can be calculated using various rules, such as the power rule, product rule, quotient rule, chain rule, and more.
    • Applications of Derivatives:
      • Finding maximum and minimum values of functions (optimization problems).
      • Determining the concavity and points of inflection of functions (curve sketching).
      • Solving related rates problems.
      • Estimating values of functions using linear approximations.
    • Common Derivatives:
      • The derivative of xn is nxn-1.
      • The derivative of ex is ex.
      • The derivative of sin(x) is cos(x).
      • The derivative of cos(x) is -sin(x).

    Integral Calculus

    • Indefinite Integrals:
      • An indefinite integral represents a family of antiderivatives of a function.
      • It's essentially the reverse process of differentiation.
      • An antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x).
      • The indefinite integral of f(x) is written as ∫f(x) dx.
    • Definite Integrals:
      • A definite integral represents the area under a curve between two specific points.
      • It is used to calculate areas, volumes, and other quantities that involve accumulation.
      • The definite integral of f(x) from a to b is written as ∫ab f(x) dx.
    • Fundamental Theorem of Calculus:
      • The fundamental theorem of calculus establishes a connection between differentiation and integration.
      • Part 1 relates the definite integral to antiderivatives.
      • Part 2 provides a method for evaluating definite integrals.
    • Applications of Integrals:
      • Calculating areas bounded by curves.
      • Determining volumes of solids of revolution.
      • Calculating work done by a variable force.
      • Solving differential equations.

    Further Concepts

    • Implicit Differentiation:
      • Finding derivatives when the relationship between the variables isn't explicitly given in the form y = f(x).
    • Related Rates:
      • Problems involving rates of change of different quantities related to each other by an equation.
    • Optimization Problems:
      • Finding maximum or minimum values of functions under certain constraints.
    • Differential Equations:
      • Equations that involve rates of change, derivatives, and solutions.
    • Sequences and Series:
      • These often appear in applications of calculus, especially in infinite sums or convergence of functions.

    Techniques

    • Integration by Substitution:- A method for evaluating integrals that involve a complex function by substituting a suitable variable.
    • Integration by Parts:- A method to evaluate certain integration integrals, used when the integrand can be split into differentiated and integrated parts.
    • Partial Fractions:- This technique decomposes a rational function into simpler fractions for integration.
    • Trigonometric Substitution:- A technique to evaluate integrals that involve trigonometric functions or expressions involving square roots of expressions.
