$$\tan 3\theta \tan 2\theta -1=0$$$$-2\frac{\cos 5\theta }{\cos 5\theta +\cos \theta }=0$$$$\left(\mathrm{sorry}\mathrm{no}\mathrm{time}\mathrm{for}\mathrm{typing}\mathrm{at}\mathrm{the}\mathrm{moment}\right)$$$$\cos 5\theta =0\wedge \cos 5\theta +\cos \theta \ne 0$$$$\theta =\pm \frac{\pi }{10}+\pi z\vee \theta =\pm \frac{3\pi }{10}+\pi z;z\in \mathbb{Z}$$
