Name the quadrant in which the angle theta lies sin theta So

Name the quadrant in which the angle theta lies. sin theta

Solution

Here I like to share one simple trick to remember that angle fall in which quadrant by seeing the value of trignometric funtion. Its,

1 quadrant -- All positive

2 quadrant --Sin positive rest negative

3 quadrant --Tan positive rest negative

4 quadrant --Cos positive rest negative So in the given question, Sin is negative , so the angle can be in 3rd or 4th quadrant, But cot is also negative (so neglecting the 3rd quadrant) , Hence ans is 4th quadrant.
