You can put this solution on YOUR website! Find tan t given that sin t=3/5 and cot(t) is negative, t is in QII
----
Since sin = y/r, y = 3 and r = 5
----
Then x = -sqrt[5^2-3^2] = -4
-----
tan(t) = y/x = -4/5

Find tan t given that sin t=3/5 and cot t < 0
sin is positive (> 0), and cot is negative (< 0), so t is in the 2nd quadrant. Also since cot is < 0, tan will also be < 0
Since y = 3 and r = 5, this is a 3-4-5 Pythagorean triple. Hence, x = - 4 (x is < 0 in the 2nd quadrant)
