It is also important that students preparing to take Calculus be able to sketch the graphs of all six basic trigonometric functions.

 
y= sin x y = cos x y = tan x in the connected mode
Domain:  Domain: Domain: All reals except , where n is an odd integer.  
Range:  [-1,1] Range:  [-1,1] Range:
 
y = tan x in the dot mode y = cot x in the connected mode y = cot x in the dot mode
Domain:  All reals except , where n is an odd integer.   Domain:  all reals except , where n is an integer Domain:  all reals except , where n is an integer
Range:  Range:  Range:   
 
   
y= sec x in the connected mode y = sec x in the dot mode y = csc x in the connected mode
Domain:   All reals except , where n is an odd integer.   Domain:   All reals except , where n is an odd integer.   Domain:   all reals except , where n is an integer
Range: Range: Range:
 
 
y = csc x in the dot mode
Domain:   all reals except , where n is an integer
Range: 

 Study each graph and be able to draw them. All functions are graphed on (-2, 2).

Check Your Understanding: (Remember to write down your answers.)

1. Memorize these six graphs and practice drawing these graphs on the Zoom7:Trigonometric Window
