## Graphs of Tangent, Secant, Cotangent, and Cosecant

*(please wait while the applet loads...)*

The applet below lets you explore the graphs of variations of the
tangent function**. **The **red** graph is **tan(x)**, and the **green** graph is a more general tangent function **Atan(kx-B)**. Use the sliders to explore the effects of changing the vertical stretch,
period, and phase shift by changing **A**, **k**,
and **B**.

By changing the formulas in the applet to **sec**, **cot**, and **csc**,
you can explore the graphs of these other trig functions as well.

Recall:

- period of tangent and cotangent = (pi)/k
- period of secant and cosecant = (2pi)/k
- phase shift = B/k
