Question 999652
Find the other trig functions of theta, given sin theta 3/7 and cos theta<0
------------
sine positive & cos negative --> Q2
---
sin = y/r
y = 3
r = 7
----
{{{x = sqrt(r^2 - y^2) = sqrt(40) = 2sqrt(10)}}}
cos = x/r
tan = y/x
---
cot = 1/tan
sec = 1/cos
csc = 1/sin
---------
Use + or minus for Q2
