<PRE><B>Question 910016</B>
determine the sign of the following: 
sin 190 degrees
190 is in QII where x and y are negative
r is ALWAYS positive
sin = y/r is negative in QII
------------------------------ 

tan 135 degrees = y/x is Positive/negative is negative
------------------------------ 

cos(-50 degrees) = x/r is Positive/positive is positive
--------------------------
