1. Do Now: From memory or using a reference, write the definition of the
six trigonometric functions below in their correct location.
sin  
csc 
cos  
sec 
tan  
cot  
2. Guided Practice: Finding Values of all six trig functions
Directions: Evaluate the remaining trig functions given the following
conditions.
8
secq =
4
sin  
csc 
cos  
sec 
tan  
cot  
Find the angle measure of 
3. Group Practice: Using the definitions above, answer the following
questions about the trig functions.
