You can put this solution on YOUR website! 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)
=√(169-144)=√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
