in which quadrant is sine negative, cosine positive, and tangent negative? (1 point) quadrant iv quadrant iii quadrant ii quadrant i
Answer
Explanation:
Step1: Recall trigonometric function signs in each quadrant
- Quadrant I: (\sin\theta>0), (\cos\theta>0), (\tan\theta = \frac{\sin\theta}{\cos\theta}>0)
- Quadrant II: (\sin\theta>0), (\cos\theta<0), (\tan\theta=\frac{\sin\theta}{\cos\theta}<0)
- Quadrant III: (\sin\theta<0), (\cos\theta<0), (\tan\theta=\frac{\sin\theta}{\cos\theta}>0)
- Quadrant IV: (\sin\theta<0), (\cos\theta>0), (\tan\theta=\frac{\sin\theta}{\cos\theta}<0)
Answer:
Quadrant IV
