**definition**:**Math****Definition**: Reflection Over the X**Axis**. A reflection of a point, a line, or a figure in the X**axis**involved reflecting the image over the x**axis**to create a mirror image. In this case, the x**axis**would be called the**axis**of reflection.**Math****Definition**: Reflection Over the**Y****Axis**A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph. These horizontal and vertical lines or

**axis**in a graph are the x-**axis**and**y**-**axis**respectively. In this mini-lesson, we will learn about the x-**axis**and**y**-**axis**and what is**x and y-axis**in geometry along with solving a few examples.The numbers placed on the

**y**-**axis**are called**y**-coordinates. The x-**axis**is a horizontal line with 0 as the origin, positive numbers on the right, and negative numbers on the left. The**y**-**axis**is drawn vertically from bottom to top with the same origin as the x-**axis**with positive numbers on top and negative numbers at the bottom.In

**y**= cos(x), the center is the x-**axis**, and the amplitude is 1, or A=1, so the highest and lowest points the graph reaches are 1 and -1, the range of cos(x). Compared to**y**=cos(x), shown in purple below, the function**y**=2 cos(x) (red) has an amplitude that is twice that of the original**cosine**graph.A

**Cartesian coordinate system**(UK: / k ɑː ˈ t iː zj ə n /, US: / k ɑːr ˈ t i ʒ ə n /) in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.Jan 25, 2022 · To reflect an equation over the

**y**-**axis**, simply multiply the input variable by -1: {eq}**y**=f(x) \rightarrow**y**=f(-x) {/eq}. This is because the input variable is the only changed since the flip is ...The two figures below show 3D views of respectively

**atan2**(**y**, x) and arctan(**y**/ x) over a region of the plane. Note that for**atan2**(**y**, x), rays in the X/**Y**-plane emanating from the origin have constant values, but for arctan(**y**/ x) lines in the X/**Y**-plane passing through the origin have constant values.
