    I 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?

    Given: sin =4/5 and cos x =-5/13 ; evaluate the following expression. (Theta: Quadrant I, x : Quadrant II.) tan 2 Theta a.) 8/3 b.) 24/7 c.) -24/7

    my outcome is -24/7 but theta is in the first quad and tan is positive in the first quad

    If theta is greater than 45 and in the first quadrant, then 2 theta is in the second quadrant where the tangent is negative.

    yes 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

    assuming you didnt make any mistakes in your calculation, then that would be the answer note- i didnt actually do the problem
