Multiple questions should not be sent by one posting.
Only questions 3 and 4  are solved

--------------------------------------------------------------

Question (3)

θ = -60o

cosθ = cos(-60o ) = cos(60o )  because cosine function is even

cosθ = cos(-60o ) = cos(60o ) = 1/2

sinθ = sin(-60o) = - sin(60o) because sine function is odd

cosecθ = 1/sinθ = 1/sin(-60o) = - 1/sin(60o) = - 2/√3

----------------------------------------------------------

Question (4)
