How to graph the secant graph

The video tutorial explains how to graph the secant function by understanding its relationship with the cosine function. It begins with a review of the cosine graph, highlighting critical points and their cyclical nature. The instructor demonstrates how to create a table of cosine values and uses these to graph the secant function, emphasizing the role of asymptotes. The tutorial concludes by finalizing the secant graph, using the cosine graph as a reference.

What is the secant function in relation to the cosine function?

• It is the integral of the cosine function.

• It is the derivative of the cosine function.

• It is the reciprocal of the cosine function.

• It is the same as the cosine function.

What is the y-value of the cosine function at π?

• Undefined

• 1

• -1

• 0

What happens to the secant function at the x-intercepts of the cosine function?

• It equals one.

• It equals zero.

• It becomes undefined.

• It reaches its maximum value.

How does the secant graph behave near its asymptotes?

• It oscillates around the asymptotes.

• It remains constant.

• It crosses the asymptotes.

• It approaches the asymptotes.

What shape does the secant graph resemble as it approaches the asymptotes?

• A circle

• A parabola

• A sine wave

• A straight line
