This video tutorial explains how to describe and graph transformations of the cosecant function. It begins by factoring the given equation to identify parameters A, B, C, and D. The tutorial then discusses the characteristics of the graph, such as period, phase shift, and vertical shift. It uses the sine function as a reference to graph the cosecant function, highlighting the relationship between the two as reciprocals. The video also covers the placement of vertical asymptotes and the concavity of the graph.

What is the first step in graphing the transformation of the given cosecant function?

• Factor the expression to fit the standard form.

How does the phase shift affect the starting point of the sine graph?

• It changes the amplitude.

• It alters the period.

• It shifts the graph vertically.

• It moves the graph horizontally.

Where do vertical asymptotes occur in the graph of the cosecant function?

• At the maximum points of the sine function.

• At the minimum points of the sine function.

• At the midline of the sine function.

• Where the sine function equals zero.

What is the relationship between the concavity of the sine and cosecant functions?

• They are both concave up at the same points.

• They are both concave down at the same points.

• They have opposite concavity at corresponding points.

• They have the same concavity throughout.

What additional factor complicates the graphing of the cosecant function?

• The presence of a vertical shift.

• The reciprocal nature of the function.

• The extra factor of 2 in front.

• The lack of an amplitude.
