Trigonometric values w.r.t. Quadrants (1st, 2nd, 3rd and 4th)

👉Important Rules for trigonometric values in 1st ,2nd ,3rd and 4th Quadrant.

{1}.  Quadrant 1st:

(90°-θ) and (360°+θ)

All Trigonometric values are Positive (+).

{2}. Quadrant 2nd: 

(90°+θ) and (180°-θ)

Only values of sine (sin) and Cosecant (cosec) is positive (+) rest all Trigonometric values are negative (-).

{3}. Quadrant 3rd:

 (180°+θ) and (270°-θ)

Only values of tangent (tan) and Cotangent (cot) is positive (+) rest all Trigonometric values are negative (-).

{4}. Quadrant 4th:

 (270°+θ) and (360° -θ)

Only values of cosine (cos) and Secant (sec) is positive (+) rest all Trigonometric values are negative (-).

#A Simple Way to remember

ADD : All values positive

SUGAR : Sine,Cosine are positive

TO : Tan, cot are positive

COFEE : cos ,sec are positive
