Graphing the secant function by using cosine

The video tutorial explains how to graph the function F(x) = 1/2 secant of x by first graphing its reciprocal function, cosine. It covers the concept of amplitude and how it affects the graph's height. The tutorial also discusses the importance of understanding the parent function, determining the X scale, and identifying asymptotes for secant graphs.

What is the first step in graphing F(x) = 1/2 secant(x)?

• Graph the reciprocal function, cosine

• Graph the cotangent function

• Graph the tangent function

• Graph the sine function

How does the coefficient 1/2 affect the cosine graph?

• It changes the period

• It shifts the graph horizontally

• It affects the amplitude

• It reflects the graph over the x-axis

What is the amplitude of the cosine graph when F(x) = 1/2 cosine(x)?

• 1/2

• 0

• 2

• 1

Where are the asymptotes located in the secant graph?

• Where the cotangent graph is zero

• Where the tangent graph is zero

• Where the cosine graph is zero

• Where the sine graph is zero

What shape do the sections of the secant graph take?

• Ellipses

• Parabolas

• Triangles

• Circles
