Consider the function. f(x) = cos 4x + V3 sin 4x (a) Use the following formula where a and b are real numbers with a > 0, A2 = 22 + b2 with A > 0, and tan(C) = b/a with – 1/2 1 decade ago. Favourite answer. Prove the identity. 4 (sin^4 x + cos^4 x) = (cos 4x + 3) _________. Left Hand Side = 4 (sin^4 x + cos^4 x) = 4sin^4 x + 4cos^4 x = (2sin²x)² + (2cos²x)². = (1 - cos 2x)² + (1 + cos 2x)². Taking out the common part i.e 4sinxcosx. f' (x)=4sinxcosx (sin^2x - cos^2x) f' (x)=-2.2sinxcosx (cos^2x -sin^2x) 2sinxcosx = sin2x and cos^x-sin^x = cos2x. f' (x)=-2sin2x.cos2x. So its -4sin4x.

Multiplying out: [itex]e^{4ix}=cos^{4}(x) + 4icos^{3}(x)sin(x) - 6cos^{2}(x)sin^{2}(x)-4icos(x)sin^{3}(x)+sin^{4}(x)[/itex]. Thus: [itex]cos(4x)+isin(4x)=cos^{4}(x)+sin^{4}(x) - 6cos^{2}(x)sin^{2}(x) + i(4cos^{3}(x)sin(x) )-4cos(x)sin^{3}(x)) [/itex]. f (x) = cos4x − sin4x = (cos2x −sin2x)(cos2x +sin2x) Reminder of trig identities: cos2x − sin2x = cos2x.
