New Trigo-equation Condition: $-3-\cos^2x+3\sin 5x\geq 0$ But $3(\sin 5x-1)\leq 0$ and $-\cos^2x\leq 0$. Then $\sin 5x=1$ and $\cos x=0$. Also the right side member must be 0: $1-\sin x=0$ $\sin 5x=16\sin^5x-20\sin^ 3x+5\sin x$ If $\sin x=1$ then $\sin 5x=1$. So $\sin x=1\Rightarrow x=\frac{\pi}{2}+2k\pi$
