If you are talking about functions in 2-dimensional space, that is, functions of the sort y = f(x), then, by definition, none can be positive in the third quadrant where y is always negative.
If you are talking about functions in 3-dimensional space, ie functions of the kind z = f(x,y), then for the third quadrant in terms of x and y (x<0 and y<0), there are infinitely many functions for which z > 0.
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
y=6x is in the third quadrant while x is negative and in the first quadrant while x is positive.
The Cartesian plane is divided into four quadrants. These quadrants are determined by the signs of the x and y coordinates: the first quadrant (positive x, positive y), the second quadrant (negative x, positive y), the third quadrant (negative x, negative y), and the fourth quadrant (positive x, negative y).
In a Cartesian coordinate system, the plane is divided into four quadrants. The first quadrant (Quadrant I) is where both x and y coordinates are positive, the second quadrant (Quadrant II) has negative x and positive y values, the third quadrant (Quadrant III) has both coordinates negative, and the fourth quadrant (Quadrant IV) features positive x and negative y values. Quadrants are typically numbered counterclockwise, starting from the upper right.
The x- and y-coordinates have the same sign in the first and third quadrants. In the first quadrant, both x and y are positive, while in the third quadrant, both x and y are negative. Therefore, the correct quadrants are Quadrant I and Quadrant III.
The tangent and cotangent functions.
The third quadrant.
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
If you are familiar with trigonometric functions defined in terms of the unit circle, the x and y coordinates are negative in the third quadrant. As a result, x/y, the ratio that defines cotangent, is positive.
y=6x is in the third quadrant while x is negative and in the first quadrant while x is positive.
In the third quadrant, both the x and y coordinates are negative. Since tangent is defined as the ratio of the opposite side to the adjacent side in a right triangle, in the third quadrant where both sides are negative, the tangent of an angle theta will be positive. Therefore, tan theta is not negative in the third quadrant.

The x- and y-coordinates have the same sign in the first and third quadrants. In the first quadrant, both x and y are positive, while in the third quadrant, both x and y are negative. Therefore, the correct quadrants are Quadrant I and Quadrant III.
There are two square root functions from the non-negative real numbers to either the non-negative real numbers (Quadrant I) or to the non-positive real numbers (Quadrant IV). The two functions are symmetrical about the horizontal axis.
If a number is located on the x-axis, it is in either the first or fourth quadrant, depending on whether it is positive or negative. If it is on the y-axis, it is in either the first or second quadrant for positive values or third or fourth for negative values. Points that lie exactly on the axes do not belong to any quadrant.
