How does the rule for a trigonometric function represent the period and amplitude of the function? 
What is the relationship among the values of sin θ, cos θ, tan θ, csc θ, sec θ, and cot θ?



please Help me Thank you I HIGHLY appreciate it <3 @divu.mkr

amplitude can be seen by the graph and for period we have to use hit and trial method... http://upload.wikimedia.org/math/9/5/1/951dbdb4cc4cf63d0f60bdcf232797c6.png
