Implicit Differentiation

Implicit differentiation is a technique used to differentiate equations where y is not isolated on one side. It involves taking the derivative of every term with respect to x and applying differentiation rules while treating y as a function of x, which allows us to find dy/dx even when y is given implicitly.

Product Rule

The product rule is necessary when differentiating expressions that are products of two functions, such as terms involving both x and y. It states that the derivative of a product of two functions is the derivative of the first times the second plus the first times the derivative of the second.

Chain Rule

The chain rule is used to differentiate composite functions. In implicit differentiation, it applies when differentiating terms that involve y, because y is a function of x. The chain rule requires multiplying the derivative of the outer function by the derivative of the inner function.

Tangent Line

The tangent line to a curve at a specific point is the line that best approximates the curve at that point. Its slope is given by the value of the derivative at that point, and the equation of the tangent line can be written using the point-slope form once the slope is determined.
