- 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)`
