Question 961195
Use the given information to find the values of the remaining five trigonometric functions.
 tan t = −8, 

pi/2 < t < &#960;
That is the 2nd Quadrant where x is negative and y is positive.
---------------------------------
Since tan(t) = y/x so y = 8 and x = -1
Then r = sqrt[8^2+1^2] = sqrt{65)
-------
 sin t= y/r , cos t = x/r , csc(t) = r/y, sec(t) = r/x, & cot(t) =  x/y
