Where does the secant graph come from?

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 key points and their significance. The tutorial then demonstrates how to graph the secant function by using the reciprocal of cosine values, identifying asymptotes, and plotting shared points. The instructor emphasizes the concept of secant as a 'flipped' version of cosine and suggests using graphing technology for verification.

What is the relationship between secant and cosine functions?

• They are identical functions.

• Secant is the derivative of cosine.

• Secant is the reciprocal of cosine.

• Secant is the integral of cosine.

What is the cosine of 0 on the unit circle?

• 0

• 1

At which angle does the cosine function have a minimum value?

• π

• 0

• π/2

What happens to the secant function at π/2?

• It is negative one.

• It is undefined.

• It is one.

• It is zero.

How is the secant graph related to the cosine graph?

• It is a shifted version.

• It is a compressed version.

• It is a flipped version.

• It is a stretched version.

What is the secant of 0?
