Answer:
2. quadrant 4
3. quadrant 2
4. quadrant 3
Step-by-step explanation:
You can refer to the picture.
2. Since [tex]tan\theta[/tex] less than 0 which means [tex]tan\theta[/tex] is negative, [tex]sin\theta[/tex] less than 0 which means [tex]sin\theta[/tex] is negative.
So, the angle lies in quadrant 4 (Cos quadrant)
3. Since [tex]tan\theta[/tex] less than 0 which means [tex]tan\theta[/tex] is negative, [tex]cos\theta[/tex] less than 0 which means [tex]cos\theta[/tex] is negative.
So, the angle lies in quadrant 2 (Sin quadrant)
4. Since [tex]tan\theta[/tex] more than 0 which means [tex]tan\theta[/tex] is positive, [tex]sin\theta[/tex] less than 0 which means [tex]sin\theta[/tex] is negative.
So, the angle lies in quadrant 3 (tan quadrant)
