Graphing of Trigonometric Functions

Today in class we learned how to graph all the trigonometric functions.

y = sin x

Domain: all real numbers

Range: [-1, 1]

Period: 2π

y = cos x

Domain: all real numbers

Range: [-1, 1]

Period: 2π

y = tan x

Domain: all, x can't equal π/2 + n(π)

Range: (-∞, ∞)

Period: π

y = csc x = 1/ sin x

Domain: all x can't equal n(π)

Range: (-∞, -1] and [1, ∞)

Period: 2π

y = sec x = 1/ cos x

Domain: all x can't equal π/2 + n(π)

Range: (-∞, -1] and [1, ∞)

Period: 2π

y = cot x = 1/tan x

Domain: all x can't equal n(π)

Range: (-∞, ∞)

Period: π
