Sketch a right triangle corresponding to the trigonometric function of the acute angle θ. Use the Pythagorean Theorem to determine the third side and then find the other five trigonometric functions of θ.
cot(θ) = 3

sin(θ)=
cos(θ)=
tan(θ)=
csc(θ)=
sec(θ)=

  2. recall that
    tanθ = 1/cotθ
    sec^2θ = 1 + tan^2θ
    csc^2θ = 1 + cot^2θ
    sinθ = 1/cscθ
    cosθ = 1/secθ

    Or, just draw a right triangle with ABC with B=90°
    Then AB=3, BC=1
    now figure the hypotenuse, and just read off the trig functions from the triangle.
