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).
