WEBThe sign of trigonometric functions in each quadrant is given in the figure below. In the first quadrant, all functions are positive, in the 2nd quadrant, only sin and cosec are positive, in the 3rd quadrant only tan and cot are positive, whereas in the 4th quadrant only cos and sec are positive.
Signs of sin, cos, tan in different quadrants - Teachoo
WEBApr 16, 2024 · To learn sign of sin, cos, tan in different quadrants, we remember. A dd → S ugar → T o → C offee. Representing as a table. What about cot, sec, cosec? We know that. tan = sin/cos. sec = 1/cos. cosec = 1/sin. cot = 1/tan. So, In 1 st quadrant - sin, cos both +ve. tan = sin/cos = +/+ = +. cosec = 1/sin = 1/+ = +. sec = 1/cos = 1/+ = +.
