Find the exact values of sin 2u, cos 2u, and tan 2u using the double.pdf

  1. Find the exact values of sin 2u, cos 2u, and tan 2u using the double-angle formulas. tan u = 5/3, 0 < u < ?/2 and Find the exact values of sin 2u, cos 2u, and tan 2u using the double-angle formulas. sin u = ?3/5, 3?/2 < u < 2? Solution we know that sin 2x = 2 tan x / (1 + tan^2 x) cos 2x = (1 - tan^2 x) / (1 + tan^2 x) tan2x= 2tan(x) / (1 - tan
