We are in Quad 4

 

r =  sqrt [ 9^2 + 4^2 ]   = sqrt  97

 

a)   sin =   -9/sqrt 97

      cos =  4/sqrt 97

      cot = -4/9

       sec =  sqrt (97)  / 4

       csc =  -sqrt (97) /4

 

b)   arctan (-9/4)   =  -66.04°

So....the angle is  360  -  66.04  =  293.96°

csc θ = 1/sin

So it would be θ = -√97/9, not θ = -√97/4
