If sinθ=−12/13 and secθ<0 , what are the values of cosθ,tanθ,cscθ,secθ , and cotθ?

sin = -12/13

sec = 1/cos       if sec <0 then cos < 0

 

sin2    + cos= 1    yields    cos = - 5/13

 

Tan = sin / cos   

csc = 1/sin

sec = 1/cos

cot = cos/sin            plug in the values of sin and cos to compute these trig values....
