Is the cotangent function positive in quadrant 3?

In the second quadrant, only sine and cosecant (the reciprocal of sine) are positive. In the third quadrant, only tangent and cotangent are positive.

Which trig functions are positive in the 3rd quadrant?

Sine and cosecant are positive in Quadrant 2, tangent and cotangent are positive in Quadrant 3, and cosine and secant are positive in Quadrant 4.

In which quadrant is the cotangent function positive?

quadrant III
In quadrant II, “Smart,” only sine and its reciprocal function, cosecant, are positive. In quadrant III, “Trig,” only tangent and its reciprocal function, cotangent, are positive.

Which trigonometric functions are positive in Quadrant I?

In quadrant I, which is “A,” all of the six trigonometric functions are positive. In quadrant II, “Smart,” only sine and its reciprocal function, cosecant, are positive. In quadrant III, “Trig,” only tangent and its reciprocal function, cotangent, are positive.

What are the trigonometric ratios of an acute angles are positive in 3rd quadrant?

In general, if lies in the third quadrant, the acute angle θ − 180° is called the related angle for θ. Finally, if θ lies between 270° and 360° the corresponding point P is in the fourth quadrant. In this quadrant, we can see that the sine and tangent ratios are negative and the cosine ratio is positive.

What trig functions are positive in which quadrants?

All the trig functions are positive in Quadrant 1. Sine and cosecant are positive in Quadrant 2, tangent and cotangent are positive in Quadrant 3, and cosine and secant are positive in Quadrant 4.

When does the angle θ lie in the first quadrant?

When the θ lies in the first quadrant: All trigonometric functions or trigonometrical ratios of the angle θ will be positive (+ve). All trigonometric functions are Sin θ, Cos θ, Tan θ, Sec θ, Cosec θ, and Cot θ. When the θ lies in the second quadrant: Only sin θ and cosec θ will be positive and the rest of all will be negative.
