    Study Notes

    Differentiation

    Definition

    • Differentiation is a mathematical operation that finds the rate of change of a function with respect to one of its variables.
    • It is a fundamental concept in calculus, used to study the behavior of functions, optimize functions, and solve problems in physics, engineering, and other fields.

    Geometric Interpretation

    • The derivative of a function at a point represents the slope of the tangent line to the graph of the function at that point.
    • The derivative can be visualized as the rate of change of the function with respect to the input variable.

    Rules of Differentiation

    • Power Rule: If f(x) = x^n, then f'(x) = nx^(n-1)
    • Product Rule: If f(x) = u(x)v(x), then f'(x) = u'(x)v(x) + u(x)v'(x)
    • Quotient Rule: If f(x) = u(x)/v(x), then f'(x) = (u'(x)v(x) - u(x)v'(x)) / v(x)^2
    • Chain Rule: If f(x) = g(h(x)), then f'(x) = g'(h(x)) * h'(x)

    Higher-Order Derivatives

    • The second derivative of a function represents the rate of change of the first derivative.
    • Higher-order derivatives can be used to study the concavity and inflection points of a function.

    Applications of Differentiation

    • Optimization: Differentiation is used to find the maximum or minimum of a function.
    • Physics: Differentiation is used to model the motion of objects, including acceleration and velocity.
    • Economics: Differentiation is used to model economic systems, including supply and demand curves.

    Notation

    • The derivative of a function f(x) is denoted as f'(x) or (d/dx)f(x).
    • The second derivative of a function f(x) is denoted as f''(x) or (d^2/dx^2)f(x).
