Question

please let me understand quadrants in trigonometry

Answer 1

Signs of Angles in Quadrants. ... Thus, in the first quadrant, where x and y coordinates are all positive, all six trigonometric functions have positive values. In the second quadrant, only sine and cosecant (the reciprocal of sine) are positive. In the third quadrant, only tangent and cotangent are positive

Answer 2

there are four quadrant in trignometry
that are quadrant 1,2,3,4 and each quadrant is equal to 90degree...
in first quadrant all the trignometric values will be positive
in 2nd quadrant the value of sin will be +ve and all will be -ve
in 3 rd quadrant the value of tan and cot will be +ve and all will negative
in 4 th quadrant the value of cos will positive and alla will -ve
