Key Concepts

Chain Rule

The chain rule is a method for differentiating composite functions, where one function is applied inside another function. It allows us to compute the derivative of the overall composite function by multiplying the derivative of the outer function evaluated at the inner function by the derivative of the inner function.

Product Rule

The product rule is a technique used in differentiation when the function being differentiated is the product of two or more functions. It states that the derivative of a product is the derivative of the first function times the second function plus the first function times the derivative of the second function.

Tangent Line

The tangent line to a curve at a given point is a straight line that touches the curve at that point without crossing it locally. It represents the instantaneous direction or slope of the curve at that specific point and is characterized by having the same derivative as the curve at the point of tangency.

Derivative

The derivative of a function is a measure of how the function's output changes as its input changes. It is interpreted as the slope of the tangent line to the graph of the function at any given point, and finding the derivative is essential for determining the behavior of functions, including their increasing or decreasing nature.
