<PRE><B>Question 1058824</B>
Analyze according to the acute angle which theta is; as if it were in quadrant 1.


{{{cos(theta)=3/sqrt(3^2+4^2)}}}


{{{cos(theta)=3/sqrt(25)}}}


{{{cos(theta)=3/5}}}


BUT are you just interested in theta, or are you really interested in WHERE the point (-3,-4) is, including the 180 degrees as part of the rotation from standard position?</PRE>
