So the sine will be negative when y is negative, which happens in the third and fourth quadrants. Why is sin positive in second quadrant? Where’s sine positive? Since sine is the second coordinate on point P, it’s going to be positive whenever that point is above the x axis.
WebFurther, these trig functions have different numeric signs (+ or -) in the different quadrants, which are based on the positive or negative axis of the quadrant. The trigonometric functions of Sinθ, Cosecθ are positive in quadrants I and II, and are negative in quadrants III and IV. WebFinally, when angle a is in Quadrant 4 (between 270° and 360°), the adjacent side is back along the positive x- direction, while the opposite side is still in the positive y- direction.Hence, Sine and Tangent are negative and only Cosine (C) is positive.Trigonometry Quadrant App. Here is a simple interactive app to illustrate the …
