Question

Determine the quadrant in which θ lies
(i) sinθ > 0, secθ < 0
(ii) cosθ < 0, cotθ < 0
(iii) cosθ > 0, cosecθ < 0

Answer 1

here is the answer for your question

1) sinθ > 0. is in 1 & 2 quadrant

secθ < 0 is in 2 & 3 quadrant


2) cosθ < 0 is in 2 & 3 quadrant

cotθ < 0 is in 2 & 4 quadrant

3) cosθ > 0 is in 1 & 4 quadrant

cosecθ < 0 is in 3 & 4 quadrant
