Multiple !i have no idea how to do ! 1.) if θ is a first-quadrant angle in standard position with p(u, v) = (3, 4), evaluate cos2θ= -7/25 7/25 -1/5 2.) what is the correct identity for cos2θ? (1-tan^2θ) / (1+tan^2θ) (2tanx) / (1+tan^2x) (1-cos2x) / (2) (sinθ) / (1+cosθ) (1+cos2θ) / (2) 3.) what is the correct identity for cos^2θ? (1-tan^2θ) / (1+tan^2θ) (2tanx) / (1+tan^2x) (1-cos2x) / (2) (sinθ) / (1+cosθ) (1+cos2θ) / (2) if you could tell me how you did it that would be very so i know how to do the rest of my hw!
