always remember rule
1. ALL 2. SILVER 3. TEA 4. CUPS
1,2,3,4 are the 4 quadrants of a 2d coordinate system
in 1st quadrant all the trigonometric functions are positive
2. in 2nd quadrant s for silver, s for sine function
so sine and it's inverse that is cosecant are positive and others are negative
3. in 3rd quadrant t for tea and t for tangent function so tan and cot func. are positive and others are negative
4. in 4th quadrant c forcups and c for cos and
sec are positive and other are negative
