Key Concepts

Implicit Differentiation

Implicit differentiation is a technique used to find the derivative of a function when it is given in an implicit form, meaning that y is not easily isolated in terms of x. Instead of explicitly solving for y, both sides of the equation are differentiated with respect to x, treating y as an implicit function of x, which usually requires applying other differentiation rules such as the chain rule and product rule.

Tangent Line

The tangent line to a curve at a given point is the line that just touches the curve at that point and has the same slope as the curve at that point. To determine its equation, after finding the derivative (which gives the slope) at the specific point, the point-slope form of a line is used to write the equation of the tangent.

Chain Rule

The chain rule is a method for differentiating composite functions, where one function is nested inside another. In cases where a function involves a composition like sin(u(x, y)), the chain rule allows one to differentiate the outer function with respect to its inner function and then multiply by the derivative of the inner function with respect to x.

Product Rule

The product rule is used when differentiating an expression that consists of the product of two or more functions. It states that the derivative of a product is given by the derivative of the first function times the second function plus the first function times the derivative of the second function. This rule is essential when dealing with expressions where different functions of x and y are multiplied together.
