**Complete the Table** | | 13.) | 14.) | 15.) | 16.) | 17.) | 18.) | 19.) | 20.) | |-------|------|------|------|------|------|------|------|------| | **Quadrant** | I | II | II | IV | II | III | IV | II | | **sin θ** | 3/5 | 5/13 | ? | ? | 1/5 | -3/7 | ? | 1/9 | | **cos θ** | ? | ? | -24/25| 15/17| ? | ? | 3/4 | ? | **Explanation:** This is a table used for solving trigonometric identities related to the sine and cosine functions within specific quadrants of the unit circle: - **Quadrant I:** Both sine and cosine are positive. - **Quadrant II:** Sine is positive, cosine is negative. - **Quadrant III:** Both sine and cosine are negative. - **Quadrant IV:** Sine is negative, cosine is positive. The table requires completing the missing values of sine and cosine for given angles situated in specific quadrants using trigonometric relationships.
