Best ResponseYou've already chosen the best response.0I have a problem and it ask for tan2theta, and theta is in the 1st quad, but when I work out the problem I get a negative result. Do that number automatically turns positive?

Best ResponseYou've already chosen the best response.0If theta is greater than 45 and in the first quadrant, then 2 theta is in the second quadrant where the tangent is negative.

Best ResponseYou've already chosen the best response.1yes theta is in the first quadrant, but you're not finding tan(theta) you're finding tan(2*theta) and its possible for 2*theta to be in the second quadrant as mertsj just stated
