A Cartesian coordinate system measured that every point individually in a plane by a couple of arithmetic coordinates, the signed distances from the location to two set perpendicular heading lines, calculated in the related unit of length. The co-ordinate system is also called Cartesian co-ordinate system.
Every position line is known as a coordinate alignment and the point where they meet is its origin. Two axes are the positions of at right angles projections point, uttered assigned distance from the origin is defined the coordinates.
This diagram represents the four quadrants of a graph. It tells that the first quadrant have only positive values for the all the trigonometric functions. The second quadrant has only the positive values for sine and cosecant functions. The third quadrant has only the positive values for tangent and cotangent functions. The fourth quadrant has only the positive values for cosine and secant functions.I hope the above explanation was useful, now let me explain about basic trigonometry
