Which of the following functions is not periodie? `|sin3x|+sin^2x` `cossqrt(x)+cos^2x` `cos4x+tan^2x` `cos2x+sinx`

Which of the following functions is not periodic? (a) |sin 3x| +sin^(2)x " (b) " cos sqrt(x)+cos^(2)x (c ) cos 4x +tan^(2)x " (d ) " cos 2x + sinx

Which of the following functions is periodic (a) cos^2x+sinx^3+"tan"(x^4) (b) cos^2x+sinx^3+tan^4x (c) cos^2x^2+sinx^3+tan^4x (d) cos2x+sin3x+tan4x

cos3x-cos2x=sin3x

Which of the following functions are periodic - (1) sin x+cos x(2)cos x+{(x)/(pi)}(3)cos pi x+{2x}(4)ln{x}+sin2x

(sinx+sin3x)/(cosx+cos3x) = tan2x

Prove the following Identities (cos 4x sin 3x - cos 2xsin x)/(sin 4x.sin x +cos 6x.cos x)= tan 2x

Prove the following Identities sin x +sin 2x + sin 4x +sin 5x = 4 cos(x/2).cos((3x)/2)sin3x

Compute the following: [[cos^2x, sin^2x],[sin^2 x, cos^2 x]]+[[sin^2x, cos^2 x],[cos^2 x, sin^2 x]]

3-2cos x-4sin x-cos2x+sin2x=0

sin3x+sin2x-sinx=4sinxcos(x/2)cos(3x/2)
