Which quadrant contains -2 -9?
7
In what quadrant is cosine negative and cotangent negative?
The second quadrant (top left).
Why is cosine negative in the third quadrant?
On a Unit Circle, the cosine is the x coordinate of the point on the circle represented by an angle. Angles greater than 90° (pi/2 radians) and less than 270° (3*pi/2 radians) are to the left of the y-axis, so x is negative. Quadrant I is the upper right quadrant (x positive, y positive) 0° < ɵ < 90° Quadrant II is the upper left quadrant (x negative, y positive) 90° < ɵ < 180° Quadrant III is the lower left quadrant (x negative, y negative) 180° < ɵ < 270° Quadrant IV is the lower right quadrant (x positive, y negative) 270° < ɵ < 360°
How do you find the quadrant number of a point?
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
What is a quadrant 2?
Quadrant II (Quadrant 2) is the region of the coordinate plane (xy-plane, a graph) that is above the x-axis and to the left of the y-axis. In this quadrant, all x values are positive and all y values are negative.
