.
sin θ = 5/6
~~~~~~~~~~~~~~~~~~~ 

If  = , then

 = +/- = +/- = +/- = +/- = +/- = +/-.


So, by knowing , you can find the modulus (the absolute value) of .

But you can not determine the sign of .

It can be  "+" (positive)  or  "-" (negative).

To determine the sign, you need an additional info.

For example, if you know to which quadrant the angle  belongs, then you can determine the sign of ,
and then you know everything.

When you know everything for  (and , of course), then you can calculate all other trigonometric functions.
