Question 825724
If secθ= 4/3 and θ terminates in Quadrant IV, find the exact values for all six trigonometric functions of θ.(sinθ,cosθ, tanθ,cscθ,secθ, and cotθ) You may leave denominators unrationalized.
***
Reference angle in quadrant IV in which sin<0,cos>0,tan<0
sec&#952;=4/3=1/cos&#952;
cos&#952;=3/4 
sin&#952;=-&#8730;(1-cos^2&#952;)=-&#8730;(1-(9/16))=-&#8730;(7/16)=-&#8730;7/4
tan&#952;=sin&#952;/cos&#952;=-&#8730;7/3
cot&#952;=-3/&#8730;7
csc&#952;=-4/&#8730;7
