How do you graph the secant, cosecant, and cotangent functions?

I am assuming that you are using a graphing calculator.

To graph ##sec x##, type in ##1/(cos x)## and graph.

graph{1/(cos x) [-6.28, 6.28, -5, 5]}

Please note that the x-axis is in radians (I switched it to ##[-2 pi, 2 pi])##. I would suggest using Zoom Trig (ZTrig) in the Zoom menu.

To graph ##csc x##, type in ##1/(sin x)##

graph{1/(sin x) [-6.28, 6.28, -5, 5]}

Finally, to graph ##cot x##, type in ##i/(tan x)##

graph{1/(tan x) [-6.28, 6.28, -5, 5]}
