1. tg 300°

   \[\frac{cos300}{sin300} = \frac{\frac{1}{2}}{-\frac{\sqrt{3}}{2}} = -\frac{1}{\sqrt{3}} = -\frac{\sqrt{3}}{3}\]

2. tg \(\frac{13\pi}{6}\)

   Тангенс \(\frac{13\pi}{6}\) не вычислен.

3. сtg \(\frac{7\pi}{4}\)

   \[ctg\frac{7\pi}{4} = \frac{cos\frac{7\pi}{4}}{sin\frac{7\pi}{4}} = \frac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}} = -1\]

4. tg 225°

   \[tg 225 = \frac{sin 225}{cos 225} = \frac{-\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}} = 1\]
