In this section, we investigate the graphs of the tangent and cotangent functions.

We learn why graphs of tan, cot, sec and cosec have a periodic gap in them (also known as a discontinuity). We learn how to sketch the graphs.

The graphs of sine and cosine were investigated under Graphs of Sine and Cosine. It is now time to investigate the remaining four trigonometric functions. The graphs appearing here will be …

Let us learn more about cotangent by learning its definition, cot x formula, its domain, range, graph, derivative, and integral. Also, we will see what are the values of cotangent on a unit circle.

Transformations of Tangent and Cotangent graphs This video provides an example of graphing the cotangent function with a different period and a vertical stretch.

From the graphs of the tangent and cotangent functions, we see that the period of tangent and cotangent are both π π. In trigonometric identities, we will see how to prove the periodicity of …
