Notes

Domain is the set of all those values at which a function is defined.
1) sin x-
Domain- R
Range- [-1,1]

2) cos x-
Domain- R
Range- [-1,1]

3) tan x-
Domain- "R"- {x:x= (2n+1)π/2,  n∈ "Z"}
Range- "R"

4) cot x-
Domain- "R"- {x:x= nπ, n∈ "Z"}
Range- "R"

5) sec x-
Domain- "R"- {x:x= (2n+1) π/2, n∈ "Z"}
Range- "R"- (-1,1)

6) cosec x-
Domain- "R"- {x:x= nπ, n∈ "Z"}
Range- "R"- (-1,1)
