Summary of Differentiation Rules

Key Questions

  • Power rule:
    if f(x) = x^n then f'(x) = nx^(n-1)

    Sum rule:
    if f(x) = g(x)+h(x) then f'(x) = g'(x)+h'(x)

    Product rule:
    if f(x) = g(x)h(x) then f'(x) = g'(x)h(x) + g(x)h'(x)

    Quotient rule:
    if f(x) = g(x)/(h(x)) then f'(x) = (g'(x)h(x) - g(x)h'(x))/(h(x))^2

    Chain rule:
    if f(x) = h(g(x)) then f'(x) = h'(g(x))g'(x)
    Or:
    dy/dx=dy/(du)*(du)/dx
