State the following differentiation rules in plain, clear English as well as symbols. For example, the quotient rule:
In symbols: 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 square of the denominator.
The power rule: d/dx (x^n) = nx^(n-1).
The product rule: d/dx (f(x)g(x)) = f'(x)g(x) + f(x)g'(x).
The chain rule: d/dx (f(g(x))) = f'(g(x))g'(x).
