- Domain and Range of Trignometric Functions and Their Graphs
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)`
