Find the values of all the trigonometric functions from the given information.
sin t=2/3, t is in quadrant II.
-----------------
By defintion sin = y/r
y = 2 and r = 3
-----
Note: x is negative and y is positive = QII
-----
x = -sqrt[r^2-y^2] = -sqrt[9-4] = -sqrt(5)
-------
sin = y/r = 2/3
cos = x/r = -sqrt(5)/3
tan = y/x = 2/-sqrt(5) = -2/sqrt(5)
------
csc = 3/2
sec = -3/sqrt(5)
cot = -sqrt(5)/2
