<PRE><B>Question 846184</B>
given f(x)=sinx. Find all values of x between 0 and 2pie such that f(x)=1/2
----
If sin = y/r, then y = 1 and r = 2
Then x = sqrt(2^2-1^2] = sqrt(3)
---
sin = y/r = 1/2
cos = x/r = sqrt(3)/2
tan = y/x = 1/sqrt(3)
-----
csc = r/y = 2
sec = r/x = (2/3)sqrt(3)
cot = x/y = sqrt(3)
