Key Concepts

Product Rule

The product rule is applied when differentiating expressions that are the product of two functions of the independent variable. Specifically, it states that the derivative of a product equals the derivative of the first function times the second plus the first function times the derivative of the second.

Chain Rule

The chain rule is a fundamental tool in calculus used for differentiating composite functions. When a variable inside another function is itself a function of the independent variable, the derivative is found by multiplying the derivative of the outer function by the derivative of the inner function.

Properties of Exponents and Logarithms

Understanding how exponents and logarithms interact is essential in simplifying and differentiating expressions where the variable appears in both the exponent and the base. These properties allow one to transform multiplicative relationships into additive ones (via logarithms) and to bring down exponents, facilitating differentiation.

Implicit Differentiation

This technique is used when the relationship between variables is given by an equation in which one variable is not explicitly solved for. Instead, you differentiate both sides of the equation with respect to the independent variable, treating the dependent variable as an implicit function and using its derivative in the process.

Logarithmic Differentiation

Logarithmic differentiation is especially useful for functions where variables are both in the base and in the exponent. By taking the natural logarithm of both sides of an equation, products become sums and exponents become coefficients, greatly simplifying the differentiation process.
