Question 873513
Given that sinø=4/7 and &#960;/2<ø<&#960;, find the values of the other 5 trigonometric functions of ø 
------
Note: t is in QII where x is negative and y is positive
-----------------------------
Since sin = y/r and sin = 4/7, y = 4 and r = 7
-----
Then x = sqrt[7^2-4^2] = -sqrt(33)
------------------------------------------
sin = y/r = 4/7
cos = x/r = -sqrt(33)/7
tan = y/x = -4/sqrt(33)
----
csc, sec, and cot are inverse of sin, cos, and tan
=====================
