This structured practice takes you through three examples of finding the equation of the line tangent to a curve at a specific point.

The instantaneous rate of change of f at a particular point is represented by the slope of the tangent line to the graph of f at that point. Let's consider each case in more detail.

Let's dive into examples of functions and their graphs, focusing on finding points where the function isn't differentiable. By examining various cases such as vertical tangents, discontinuities, and sharp turns, …

Learn how to generalize the idea of a tangent plane into a linear approximation of scalar-valued multivariable functions.

Let's extend trigonometric ratios sine, cosine, and tangent into functions that are defined for all real numbers. You might be surprised at how we can use the behavior of those functions to model real …
