Question 790380
csc A =−5,
270° < A < 360° find the other five trigonometric functions
***
Reference angle (A) is in quadrant IV where sin<0, cos>0, and tan<0
sin A=(1/csc A)=-1/5
cos A=&#8730;(1-sin^2(A))=&#8730;(1-1/25)=&#8730;(24/25)=&#8730;24/5
sec A=1/cos A=5/&#8730;24=5&#8730;24/24
tan A=sin/cos=-1/&#8730;24=-&#8730;24/24
cot A=1/tan A=-&#8730;24
