Values of Ratios
Category : 10th Class
1. \[\text{sin}\theta \]: It always lies between -1 and 1
i.e. \[\text{-1}\le \text{sin}\theta \le 1\]
2. \[\cos \theta \]: It always lies between -1 and 1
i.e. \[\text{-1}\le \cos \theta \le 1\]
3. \[\tan \theta \]: It can take any value in between \[-\infty \]and\[\infty \].
i.e. \[-\infty \le \tan \theta \le \infty \]
4. \[\cot \theta \]: It takes the any value in between \[-\infty \]and\[\infty \].
i.e. \[-\infty \le \cot \theta \le \infty \]
5. \[\sec \theta \]: It can take any value except the values lies between -1 and 1.
i.e. \[\sec \theta \le -1\] and \[\sec \theta \ge 1\]
6. \[co\sec \theta \]: It can take any value except the values lies between -1 and 1.
i.e. \[co\sec \theta \le -1\] and \[co\sec \theta \ge 1\]
