In what quadrant is cos negative
WebDetermining the quadrants in which the cotangent is positive or negative. By definition of the cotangent: cotangent is the ratio of cosine to sine. Therefore, the sign of the cotangent … WebWe first describe trigonometric functions in terms of ratios of two sides of a right angle triangle containing the angle θ. θ. With reference to the above triangle, for an acute angle θ θ (that is, 0 ≤ θ< π/2 0 ≤ θ < π / 2 ), the six trigonometric functions can be described as follows: Definition 1.36.
