Solution

Problem 3 :

cos θ ; (√19, 9)

Solution

Problem 4 :

sin θ ; (3, -4)

Solution

Problem 5 :

sin θ ; (-6, 4)

Solution

Problem 6 :

cos θ ; (2, -2)

Solution

Problem 7 :

cot θ ; (-7, √15)

Solution

Problem 8 :

cos θ ; (-5, -12)

Solution

Problem 9 :

sin θ ; (-√7, 3)

Solution

Problem 10 :

tan θ ; (-11, -2)

Solution

 1)  tan θ  = 9/42)  sec θ = 3/√53)  cos θ = √19/104)  sin θ = -4/55)  sin θ = 2/√13 6)  cos θ = 1/√27)  cot θ = √15/-78)  cos θ = -5/139)  sin θ = 3/410)  tan θ  = 2/11
