Given :-
Concept to know :-
We know that the trigonometric functions of certain angles in terms of angle in Quadrant are
Also we know that ,
Using these formula We get ,
---------------------------------------------------------------
So, the required answer is
-----------------------------------------------
Know more :-
- sin(-A) = -sinA
- cos(-A) = cosA
- tan(-A) = -tanA
- csc(-A) = -cscA
- sec(-A) = secA
- cot(-A) = -cotA
In Quadrant - 1 :- All ratios are positive
In Quadrant- 2 :- sin, csc are positive
In Quadrant- 3 :- tan , cot are positive
In Quadrant-4 :- sec, cos are positive
