when we can say ∅ lies in 4th quadrant then here cos∅ , sec∅ will be positive , but all sin∅, cosec∅, tan∅, cot∅ must be negative.
in 1st quadrant all trigonometric identities are positive .
2nd quadrant , sin∅, cosec∅ positive , rest negative,
3rd quadrant , tan∅, cot∅ positive rest are negative .
in 1st quadrant all trigonometric identities are positive .
2nd quadrant , sin∅, cosec∅ positive , rest negative,
3rd quadrant , tan∅, cot∅ positive rest are negative .
