As you can see by studying the table of cotangent values and the graph of the cotangent function, the cotangent value is negative for all angles for which the sine and cosine have a different sign (i.e. in Quadrant II and Quadrant IV), and positive for all angles for which the sine and cosine have the same sign (i.e. ...

What quadrants is cot negative?

In Quadrant IV, sec ⁡ θ \displaystyle \sec{\theta} secθ is positive, csc ⁡ θ \displaystyle \csc{\theta} cscθ and cot ⁡ θ \displaystyle \cot{\theta} cotθ are negative.

What is negative cotangent equal to?

cot ⁡ The two equations express that cot of negative angle is always equal to negative of cot of angle. ⁡ ⁡ It is called cot of negative angle identity and generally used as a formula in trigonometry mathematics.
