Trigonometric Functions
We denote and define trigonometric functions as follows.
Function | Domain | Range |
Y=Sinx | R | -1 ≤ Y ≤ 1 |
Y=Cosx | R | -1 ≤ Y ≤ 1 |
Y=Tanx | {x: x ∈ R and x ≠(2n+1) } | R |
Y=Cotx | {x: x ∈ R and x ≠n } | R |
Y=Secx | {x: x∈ R and x≠(2n+1) } | y ≥1, y ≤ -1 |
Y=Cosecx | {x: x∈R and x≠n } | y ≥1, y ≤ -1 |
