Graphing the Secant Function with a Change in Period and Reflection

The video tutorial covers graphing secant and cosecant functions by using their reciprocal functions. It explains the process of determining amplitude, period, X-scale, phase shift, and vertical translation. The teacher also reviews cosine graphing, highlighting the effects of negative coefficients and the concept of asymptotes in secant graphs. School announcements about upcoming events and meetings are also included.

What is the amplitude of the function y = -2 cosine(1/2 X)?

How do you determine the period of a function given the value of B?

Explain how to find the phase shift of a function.

How does the X scale affect the graph of a cosine function?

What does a negative sign in front of a cosine function indicate about its graph?

Describe how to graph the secant function based on the cosine function.

What is the significance of asymptotes in the graph of the secant function?
