3rd quadrant

Explanation:

By definition

sintheta="Perpendicular (P)"/ "Hypotenuse(H)"

cottheta=" Base(B)"/ "Perpendicular(P)"

"Hypotenuse is always">0

So sintheta<0," " "when (P)" <0->"theta in 3rd or 4th quadrant"

Again
cot theta>0," " "When B and P both" > "or" <0->"theta in 1st or 3rd quadrant"
In 1st quadrant B and P both >0
In 3rd quadrant B and P both <0

Hence the two given conditions will be satisfied if theta is in 3rd quadrant
