Study Notes

Derivation of Algebraic Functions

  • Algebraic functions are functions that can be constructed using a finite number of arithmetic operations (addition, subtraction, multiplication, division, and taking roots) on polynomials.

  • The derivative of an algebraic function represents the instantaneous rate of change of the function.

  • Derivatives are essential in optimization problems to find maxima and minima of functions and in applications like determining the slope of a tangent line to a curve.

Rules of Differentiation

  • Constant Rule: The derivative of a constant is zero. (d/dx(c) = 0)

  • Power Rule: The derivative of xn is nxn-1.

  • Sum/Difference Rule: The derivative of a sum or difference of functions is the sum or difference of their derivatives. (d/dx(f(x) ± g(x)) = f'(x) ± g'(x))

  • Constant Multiple Rule: The derivative of a constant times a function is the constant times the derivative of the function. (d/dx(cf(x)) = c*f'(x))

  • Product Rule: The derivative of the product of two functions is the first function times the derivative of the second plus the second function times the derivative of the first. (d/dx(f(x)g(x)) = f(x)g'(x) + g(x)f'(x))

  • Quotient Rule: The derivative of the quotient of two functions is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the denominator squared. (d/dx(f(x)/g(x)) = (g(x)f'(x) - f(x)g'(x)) / (g(x))2)

  • Chain Rule: The derivative of a composite function is the derivative of the outer function evaluated at the inner function, multiplied by the derivative of the inner function. (d/dx(f(g(x))) = f'(g(x)) * g'(x))

Derivatives of Polynomials

  • Polynomials are algebraic functions. The derivative of a polynomial can be found by applying the power rule and sum/difference rules iteratively.

  • Example: To find the derivative of 3x2 + 2x + 1, apply the power rule (first term becomes 6x), sum/difference rules to rest of the terms (second term becomes 2 and the third term becomes zero).

Applications of the Derivative

  • Tangent Lines: The derivative at a point represents the slope of the tangent line to the graph of the function at that point.

  • Optimization: Derivatives are critical in finding the maximum or minimum values of a function. Critical points (where the derivative is zero or undefined) are key to identifying these extrema.

  • Rates of Change: Derivatives represent instantaneous rates of change. This is useful across various applications, like determining velocity or acceleration in physics or the rate of growth in biology.

Products and Quotients of Functions

  • The Product Rule allows us to find the derivative of a function that is the product of two other functions.

  • The Quotient Rule allows us to find the derivative of a function that is the quotient of two other functions.

  • These rules are important since many functions encountered in applications have products or quotients of simpler functions.

Derivatives of Composite Functions

  • The chain rule is essential for finding the derivative of composite functions—functions within functions.

  • It provides a systematic approach to finding the derivative of a nested function.

  • The derivative of an outer function is applied to the inner function, then multiplied by the inner function's derivative.

  • This is crucial when differentiating functions like sin(x2) or e(3x) since they involve a composition of functions.
