About. Transcript. Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Example 1: Plot the point (-3, 2) on a cartesian plane. Solution: As the coordinate is of the form (-, +) hence, the point lies in the second quadrant. We move 3 spaces to the left of the origin and then 2 spaces upwards to get our point. Example 2: State which quadrants the following points lie in.
The angle created is the reference angle. The values of the trigonometric functions of the angle of rotation and the reference angle will differ only in their sign \((+,-) .\) On the next page are examples for Quadrants \(\mathbb{1}\), III, and IV. The process for finding reference angles depends on which quadrant the angle terminates in. Examples
Dec 10, 2023 · A quadrant is a designated area on a Cartesian plane, created by the intersection of the X and Y axes. In this plane, four quadrants are formed, each with its unique traits. The first quadrant, in the upper right, has positive x and y coordinates. The second quadrant, in the upper left, has negative x and positive y coordinates, and so on.
