In mathematics, a quadrant refers to one of the four sections formed by dividing a coordinate plane into four equal parts

In mathematics, a quadrant refers to one of the four sections formed by dividing a coordinate plane into four equal parts. The coordinate plane consists of two perpendicular number lines called the x-axis and y-axis. The x-axis represents horizontal values (left or right), and the y-axis represents vertical values (up or down).

The four quadrants are typically labeled as follows:

1. First Quadrant (Q1): This quadrant is located in the upper right portion of the coordinate plane, with both x and y-values being positive.

2. Second Quadrant (Q2): This quadrant is located in the upper left portion of the coordinate plane, with x-values being negative and y-values being positive.

3. Third Quadrant (Q3): This quadrant is located in the lower left portion of the coordinate plane, with both x and y-values being negative.

4. Fourth Quadrant (Q4): This quadrant is located in the lower right portion of the coordinate plane, with x-values being positive and y-values being negative.

Knowing the quadrant of a point on a coordinate plane is useful for identifying the signs of the x and y-values and can help in various mathematical calculations, such as finding distance and direction. It is also important in trigonometry, as the signs of the trigonometric functions (sine, cosine, tangent, etc.) vary across the quadrants.
