So 1 cos 4x = sin^2 4x = ( sin 4x )^2 = 4 sin&2 2x cos ^2 2 x in this way you can able to get many form of this expression Sponsored by PureCare Knee Protector Why are knee surgeons excitedWe will determine the value of cos 1° using the cos2x identity We know that cos2x = cos 2 x sin 2 x and sin 60° = √3/2, cos 60° = 1/2 Since 2x = 1°, x = 60° Answer Hence, integral ofAnswer to Solved Lim as x approaches 0 2cos3x cos 4x / x know Math;

 If √2cos(x)1 = (1√3)/2, you can solve for x directly, and then calculate 4x, and its cosine There may be more than one answer The second equation may have a different set of = cos^2(2x) 1 cos^2(2x) cos(2x) => write in terms of cos(2x) = 2cos^2(2x) cos(2x) 1 let y = of cos(2x) then 2cos^2(2x) cos(2x) 1 becomes 2y^2 y 1 The given solutions are x = 0, 2 π / 7, 4 π / 7 and 6 π / 7 My first approach was to write the whole thing in terms of cos x this gave, 0 = ( cos x − 1) ( 8 cos 3 x 4 cos 2 x − 4 cos x
