lution. ** Since period of the $\sec$ is $2\pi$, therefore \begin{align*} 6 \sec(2 x-3) & = 6 \sec(2 x-3... lution. ** Since period of the $\cos$ is $2\pi$, therefore \begin{align*} \cos (5 x+4) & = 6 \cos(5x+4+2... ** Since the period of \( \sin \) is \( 2\pi \), therefore: \begin{align*} 7 \sin(3x + 3) &= 7 \sin(3x +... ** Since the period of \( \sin \) is \( 2\pi \), therefore: \begin{align*} 5 \sin(2x + 3) &= 5 \sin(2x +
