The x-and the y-axes of the two dimensional Cartesian coordinate system divide the plane in four. Each of these is a quadrant.

The difference between plane and spherical triangles is that plane triangles are constructed on a plane, and spherical triangles are constructed on the surface of a sphere. Let's take one example and run with it. Picture an equilateral triangle drawn on a plane. It has sides of equal length (naturally), and its interior angles are each 60 degrees (of course), and they sum to 180 degrees (like any and every other triangle). Now, let's take a sphere and construct that equilateral triangle on its surface. Picture an "equator" on a sphere, and cut that ball in half through the middle. Set the top half on a flat surface and cut it into four equal pieces. Now if you "peel up" the surface of one of those quarters and inspect that triangle, it will have three sides of equal length, and will have three right angles. Not possible on a plane, but easy as pie on the surface of a sphere. Spherical trig is the "next step up" from plane trig.

A sphere is not usually divided into 4 quadrants. Dividing by 2 along each of the 3 orthogonal axes partitions the sphere into 8.

There are four quadrants. They are represented by Roman numerals : I(one), II(two), III(three), IV(four). The first quadrant contains all positive points , (+x, +y) The second quadrant contains negative x's and positive y's , (-x, +y) The third quadrant is all negative , (-x, -y) The fourth quadrant has negative y's and positive x's , (+x, -y)

cos20 x cos40 x cos80 = 0.0300 radians = 0.125 degrees (the value for radians is given to four decimal places, the value in degrees is exact)

The coordinate plane is divided into four quarters by the axes. These are the four quadrants.

The four region are called quadrant-the first quadrant is the upper right side of the cartesian plane.-the second quadrant is the upper left side of the cartesian plane.-the third quadrant is the lower left side of the cartesian plane.-the fourth quadrant is the lower right side of the cartesian plane.

It is the Cartesian plane or coordinated grid

The intersecting x- and y-axes divide the coordinate plane into four sections.

A coordinate grid has just one large section displaying data varying from (0,0) to (infinity,infinity). On the other hand, a coordinate plane is much different. A coordinate plane has four sections, (+,+), (+,-), (-,+), and (-,-). Theese four sections are all in oposite corners of a grid. I hope this helped!!
