Study Notes

Derivatives and Their Properties

Definition of the Derivative: The derivative of a function f(x) with respect to x, denoted as f'(x) (or dy/dx), is the limit as h approaches 0 of [f(x + h) - f(x)] / h. This represents the instantaneous rate of change of the function at a particular point.

Alternate Notation

Prime Notation (f'(x)): Standard notation for the derivative.
Fractional Notation (dy/dx): Represents the derivative of y with respect to x. d/dx(f(x)) is also equivalent.

Differentiability and Continuity

Differentiable at a Point: A function f(x) is differentiable at x = a if f'(a) exists. Differentiable on an interval means the derivative exists for every point in that interval.
Continuity Implies Differentiability (but not vice versa): If a function is differentiable at a point, it is continuous at that point. The converse is not true – a continuous function may not be differentiable at every point. The absolute value function, |x|, is a notable example.

Basic Derivative Properties and Formulas

Sum/Difference Rule: The derivative of a sum or difference of functions is the sum or difference of their individual derivatives. (f(x) ± g(x))' = f'(x) ± g'(x)
Constant Multiple Rule: The derivative of a constant multiplied by a function is the constant multiplied by the derivative of the function. (cf(x))' = cf'(x)
Derivative of a Constant: The derivative of a constant is 0. (d/dx(c) = 0)
Power Rule: The derivative of xⁿ is nx^n-1. (d/dx(xⁿ) = nx^n-1)

Derivatives of Trigonometric Functions

Derivatives of Trig Functions: Provides the derivatives for sine, cosine, tangent, cotangent, secant, and cosecant.

Derivatives of Exponential and Logarithm Functions

Derivative of e^x and a^x: The derivative of e^x is e^x, and for a^x it's a^x * ln(a).
Derivative of ln(x): The derivative of ln(x) is 1/x, only valid for x > 0.

Derivatives of Inverse Trigonometric Functions

Derivatives of inverse trig functions: Provides the formulas for differentiating inverse sine, cosine, tangent, cotangent, secant, and cosecant.

Chain Rule

Chain Rule (Forms): The derivative of a composite function (f(g(x))) is f'(g(x)) * g'(x). An alternative form is dy/dx = (dy/du)(du/dx).
Identifying Inside/Outside Functions: Break down the function into an outer and inner function to apply the chain rule effectively. The "outside" function is applied last during evaluation.

Implicit Differentiation

Implicit Differentiation: Finding the derivative of "y" with respect to "x" when the function is not explicitly solved for "y". This requires the chain rule for any occurrences of "y".
Related Rates Problems: Used to find the rate of change of one variable with respect to another when the variables are related by an equation.

Higher Order Derivatives

Higher Order Derivatives: Successive derivatives of a function (second derivative, third derivative, etc.).
Notation: Higher order derivatives are often denoted using double, triple, quadruple primes, or as f⁽ⁿ⁾(x).
Polynomials and Higher Order Derivatives: The k^th derivative of a polynomial of degree n is 0 for k > n (n+1).
