Question

What trig functions are negative in quadrant 2?

Answer 1

The trigonometric functions negative in Quadrant 2 are:

Tan
Cot
Cos
Sec

So all these trigonometric functions will give negative answers in Quadrant 2 if any angle lies between `90^0` and `180^0` are given with these trigonometric functions.

Note:-

Only the trigonometric functions Sin and Cosec are positive in Quadrant 2.

These following trigonometric functions are positive in their respective Quadrants-

Quadrant 1 - All Trigonometric functions are positive
Quadrant 2 - Sin & Cosec are positive
Quadrant 3 - Tan & Cot are positive
Quadrant 4 - Cos & Sec are positive
