x + 1) = 3 has the general solution:3x – cos x sin3The equation 4 ( sin x cos (n pi / 4) + ( 8 /pi) ( npi/ 2) + ( 3 pi /8)n pi (+/– ) (5 pi / 8) (n pi/4) + ( 7 pi / 4)4 sin x cos x (cos^2 x – sin^2 x) = 3 – 42 sin 2x cos 2x = – 1sin 4x = – 1( i got it till here but how is below equation dervied)4x = 2n * pi + 3pi/2
