TRICK OF TRIGONOMETRY- This rule of trigonometry is very important and helps us to determine the sing of trigonometry ratios in different quadrants. There are four quadrants nd in every quadrant we hv different sign of the trigonometric ratios.
1st Quadrant- A (all +ve)
2nd Quadrant- S (sine & cosec +ve)
3rd Quadrant- T (tan& cot +ve)
4th Quadrant- C (cos& sec +ve)
