draw the triangle: adjacent+.7, hypo, 1.0, opposite .51
Tant=.51/.70, sint=.51/1.0, and so on.
are you meant t is negative?

cost >0 and tant< 0 , then t is in IV
if cos t = .7 = 7/10, then my triangle is 7  √51  10
sint = √51/10 , csc t = 10/√51
cos t = 7/10, sec t = 10/7
tan t = V51/7 , cot t = 7/√51
