The equation, with restriction on x, is the terminal side of an angle theta on standard position.
-3x+y=0,x is less than or equal to 0
Theta is in QII or QIII
----------------
y = 3x
tan(theta) = 3 = y/x
Since x is negative, y must be negative.
y = -3 and x = -1
Therefore r = sqrt(3^2+1^2] = sqrt(10)
--------------------------------------------
sin theta= y/r = -3/sqrt(10)
-----------
cos theta= = x/r = -1/sqrt(10)
-------------
tan theta= y/x = 3
-----------------
Note: csc, sec, and tan are the inverse of sin, cos, and tan.
