UNIT 6: Trigonometric Functions STUDY GUIDE

Find the six trig functions of the angle θ for the given triangle.

• sinθ = 4/5 cosθ = 3/5 tanθ = 4/3 cscθ = 5/4 secθ = 5/3 cotθ = 3/4

• sinθ = 3/5 cosθ = 4/5 tanθ = 3/4 cscθ = 5/3 secθ = 5/4 cotθ = 4/3

• sinθ = 5/4 cosθ = 4/3 tanθ = 5/3 cscθ = 4/5 secθ = 3/5 cotθ = 3/4

• sinθ = 3/4 cosθ = 4/5 tanθ = 3/5 cscθ = 4/3 secθ = 5/4 cotθ = 5/3

Find the six trig functions of the angle θ for the given triangle.

• sinθ = 7.5/8.5 cosθ = 4/8.5 tanθ = 7.5/4 cscθ = 7.5/8.5 secθ = 8.5/4 cotθ = 4/7.5

• sinθ = 8.5/7.5 cosθ = 4/7.5 tanθ = 8.5/4 cscθ = 7.5/8.5 secθ = 7.5/4 cotθ = 4/8.5

• sinθ = 4/8.5 cosθ = 7.5/4 tanθ = 4/7.5 cscθ = 8.5/4 secθ = 4/7.5 cotθ = 7.5/4

• sinθ = 7.5/4

  cosθ = 4/8.5 tanθ = 7.5/8.5 cscθ = 4/7.5 secθ = 8.5/4 cotθ = 4/7.5
