Question 570020
What is the trig. functions if sin t =12/13, terminal point t is in the second quadrant ? 
You are working with a right triangle where the opposite side and hypotenuse are given as 12 and 13, respectively. By the Pythagorean Theorem, the adjacent side=√(13^2-12^2)
=&#8730;(169-144)=&#8730;25=5. In quadrant II, sin>0, cos<0, tan<0, cot<0, sec<0, csc>0
cos t =-5/13	
tan t =-12/5
cot t =-5/12	
sec t =-13/5	
csc t = 13/12
