cosx} =1-2(4sin 2 x.cos 2 x) =1-8sin 2 x.co sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x It is also interesting that sin18 (cos 72), sin36, (cos 54), sin54 (cos 36) and sin72 (cos 18) all come out as exact and easily represented ratios, just like sin30, sin45 and sin60, and is this due to 18 degrees =pi/10 and so on? cos(2x) = sin(3x) so cos(2x) = sin(x)cos(2x) + cos(x)sin(2x) or cos(2x)- sin(x)cos(2x) = cos(x)(2sin(x)cos(x)) I have two problems I am stuck on, if you could show me how to solve the problems it would be much appreciated. 1) Find sin 2x, cos 2x, and tan 2x from the given information. tan x = − 1/6, cos x > 0 sin 2x = cos 2x = tan 2x = math.
