Web225 ° = 225 ° · π 180 ° = 5 π 4 225 ... Table 1.9 shows the values of sine and cosine at the major angles in the first quadrant. From this table, we can determine the values of sine and cosine at the corresponding angles in the other quadrants. ... Find the (exact) missing coordinate value of each point and b. find the values of the six ... Web225 ° can be rewritten as 225 ° = 180 ° + 45 ° = 2 × 90 ° + 45 °. Thus 225 ° belongs to the third quadrant. It is known that the values of sines are negative - in the third quadrant. It is also known that, sin 180 ° + x ° = - sin x °. Thus, sin 225 ° = sin 180 ° + 45 ° = - sin 45 ° = - 1 2. Therefore, the value of sin 225 ° is ... akute appendizitis icd 10
