These Videos employ a method to graph the Cosecant and Secant Functions (using the graphs of sine and cosine). Also covers the domain, period, range, and equations of asymptotes.
Graph Cosecant Functions
Cosecant 1: http://youtu.be/sK8ECyJRrgE
y=csc(x)
Cosecant 2: http://youtu.be/Wso94ULXlEA
y=2csc(x) and y= —2csc(x)
Cosecant 3: http://youtu.be/8E3u0dy9wb0
y=csc(2x/3)
Graph Secant Functions
Secant 1: http://youtu.be/ETtNBdWaeTY
y=sec(x)
Secant 2: http://youtu.be/skPWtIWPfB8
y=(—1/2)sec(x)
Secant 3: http://youtu.be/hP9Bqb-5hRo
y=3sec(2x)
