Question 874958
"IF SIN=2/3 THEN REMAINING TRIGONOMETRIC FUNCTIONS"
---------------
{{{cos(x) = sqrt(1 - sin^2(x)) = sqrt(1 - 4/9)}}}
= {{{cos(x) = sqrt(5)/3}}}
------------
tan = sin/cos
cot = cos/sin
sec = 1/cos
csc = 1/sin
----------------
If sin(x) = 2/3, x could be in Q1 or Q2.
That affects the signs of the other functions.
