Learn about the tangent graph and its properties through an engaging video lesson on Khan Academy.

Sal draws the graph of the tangent function based on the unit circle definition of the function.

Discover how the derivative of a function reveals the slope of the tangent line at any point on the graph. We'll explore how to use this powerful tool to determine the equation of the tangent line, …

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

Sal draws the graph of the tangent function based on the unit circle definition of the function.

Let's explore the process of finding the equation of the tangent line to the graph of f (x) = x³ - 6x² + x - 5 at x = 1. By calculating the derivative and evaluating it at x = 1, we determine the slope …

Given the graph of a function, can you identify the graph of its antiderivative?

Sketch the graph of a transformed sine, cosine, and tangent function written in standard form by using transformations for at least a two-period interval, including both positive and negative …

From the definition you can sketch the trig function such as sin, cos and tan. You can redefine the trig function using a non-unit circle by making use of properties of similarity.

Sal introduces arctangent, which is the inverse function of tangent, and discusses its principal range.
