You can put this solution on YOUR website! If Cos theta = 12/13 and theta is in quadrant 4, then find (expressed as a fraction) cot theta.
-----
By definition cos = x/r , so x = 12 and r = 13
-----
Since y is negative in QIV,
y = -sqrt[13^2-12^2) = -5
-----
Ans: cot(t) = x/y = 12/(-5) = -12/5 = -2.4
