The root rule is a derivative rule used to find the derivative of a function that involves a radical expression. It states that the derivative of √(x) is equal to 1/(2√(x)).
The chain rule is another derivative rule used when we have composite functions. It allows us to find the derivative of functions within other functions.
The power rule is a basic derivative rule used for functions involving exponents. It states that if we have x raised to some power n, then its derivative is nx^(n-1).
The quotient rule is used to find derivatives when we have fractions or ratios involved in our function. It helps us determine how changes in one part affect changes in another part of the function.
