Product Rule
The rule for differentiating the product of two functions: d/dx [f(x)g(x)] = f'(x)g(x) + f(x)g'(x).
Quotient Rule
The rule for differentiating the quotient of two functions: d/dx [f(x)/g(x)] = (g(x)f'(x) - f(x)g'(x)) / [g(x)]^2.
Chain Rule
The rule for differentiating composite functions: d/dx [f(g(x))] = f'(g(x))g'(x).
