Introduction to Online Graphing Calculator?

The Online Graphing Calculator is a versatile tool that enhances your learning ability and analyzes cartesian coordinates in graphical representation. You can give the equation or points of coordinate planes, and it can easily plot a graph in a few seconds.

Graphing Calculator with Steps

It is a helpful tool for everyone, especially for researchers or students who did research work through the mathematical data analysis method, where the coordinate grid process is commonly used to represent plane coordinates into graphs.

What is a Coordinate Grid or Graphing?

A coordinate grid, also named a coordinate plane or cartesian plane, is a two-dimensional plane with a horizontal axis (x-axis) and a vertical axis (y-axis). The intersecting point at which they meet is called the origin.

This system is used to plot points, lines, and curves into graphical representations in mathematical data analysis or scientific study.

How to Find Grid Coordinates?

To find the grid coordinates of a point on a coordinate plane, you need to identify the x coordinates on the horizontal plane and the y coordinates on the vertical plane. Here’s a step-by-step guide on how to find the grid coordinates.

Steps to Finding Grid Coordinates:

If you have the equation, then you can assume one of the coordinate point to find the order pair coordinates that is used in sketching the graph. If you have an equation or points, then you can easily find it for a graphical representation of cartesian coordinates.

Step 1: Identify the point on the coordinate grid for which you need to find the coordinates.

Step 2: Draw the perpendicular lines on the axes in which there is a vertical line to the x-axis. And draw a horizontal line to the y-axis. The central point where both lines intersect is called its origin (0, 0)

Step 3: Now, point out the value of the x-coordinate on the x-axis of the graph

Step 4: Now, point out the value of the y-coordinate on the y-axis of the graph

Step 5: Lastly, combine the x-coordinate and y-coordinate into an ordered pair (x,y), in which pair coordinates are met with the help of a line on a graph that shows their position in a graph.

You can further understand this graphing coordinate concept with the help of our coordinate grid or graph calculator.

Practical Example of Graphing Coordinates:

Let's see some examples of graphing coordinates and their graphical representation in a solution for conceptual clarity.

Example:

On a grid, plot point A which has coordinates (-2,4), point B with coordinates (3,-2), and point C with coordinates (-4, -3).

Solution:

For straight lines:

Draw the graph of y = 2x -1.

Solution:

The possible point is given as an x-value,

$$ (4, ?),\; (2, ?),\; (-2, ?) $$

Now calculate the y-values using y = 2x - 1,

For the first point x = 4, so

$$ y \;=\; 2 \times 4 - 1 $$

$$ =\; 7 $$

The coordinates of these points are (4,7).

For the second point x = 2, so

$$ y \;=\; 2 \times 2 - 1 $$

$$ =\; 3 $$

The coordinates of the second point are (2,3).

For the third point is (-2, -5).

The graph of a straight line using these points is:

What is the difference between grid and surface coordinates?

The grid coordinates and surface coordinates are both related in coordinate representation but in different contexts and scales in coordinate geometry. Their differences are

Grid Coordinates

Grid coordinates are the points that are located on a cartesian coordinate system in a two-dimensional plane. The two-dimensional system consists of a horizontal x-axis and a vertical y-axis that intersect at the origin (0, 0) on a graph.

It is used to plot points, lines, and curves in a 2-D plane because it is used in various applications such as plotting locations on maps, navigation systems, and computer graphics.

Surface Coordinates

Surface coordinates are used to describe points on a three-dimensional surface. They can refer to spherical or cylindrical coordinates to various coordinate systems that are present in three-dimensional Cartesian coordinates (x, y, z) space.

In Spherical Coordinates, its coordinates are (ρ, θ, φ) instead of (x,y,z), where ρ is the radius, θ is the angle, and φ is the polar angle. In Cylindrical Coordinates its coordinates are (r, θ, z), where r is the radial distance, θ is the angular coordinate, and z is the height.

How to convert grid coordinates to longitude and latitude?

For the conversion of grid coordinates to geographic coordinates (longitude and latitude) is a geospatial application that depends on the specific projection and coordinate system used in the grid coordinates. Here are some steps to describe on how to perform this conversion:

  1. Identify the Grid Coordinate System that includes the Universal Transverse Mercator (UTM), State Plane Coordinate System (SPCS), or other local systems.
  2. Determine the projection of the curved surface (that curved form after finding the coordinates points on a graph) of Earth into a flat plane.
  3. Then use the Geographic Information System (GIS) software and it provides the corresponding longitude and latitude.

How to do rotations on a coordinate grid?

For the rotation of a point or a shape on a coordinate grid, first find the changing position based on a given angle on a specific point at the origin (0, 0). Lets us see how to perform rotations on a coordinate grid:

When you rotate a point (x,y) around at the origin by an angle θ, the new coordinates (x′,y′) can be found using the following formulas:

  • $$ x′ \;=\; xcos⁡(θ) − ysin⁡(θ) $$
  • $$ y′ \;=\; xsin⁡(θ) + ycos⁡(θ) $$

Steps for Rotation:

  1. Identify the Rotating points as P(x,y).
  2. Find the Angle of Rotation θ(in degrees or radians) by which you want to rotate that point.
  3. If your angle θ is in degrees, then convert it to radians using the formula θ radians = θ degrees × 180π.
  4. Then use the rotation formulas to calculate the new coordinates (x′, y′).

When a rectangle is graphed on a coordinate grid which transformation occurs?

When a rectangle is graphed on a coordinate grid, various transformations can be applied to it, which are the rotations, reflections, and dilations. This transformation affects the position, orientation, or size of the rectangle in a specific way.

  1. Translation:

When the rectangle translates without changing its shape, size, or orientation, each vertex (x, y) of the rectangle is moved with the same distance in one direction then after translation(a, b) new vertices are (x + a, y + b).

  1. Rotation:

When you rotate the rectangle around at the origin, for a certain angle the orientation of the rectangle changes, but its shape and size remain the same.

If a point (x, y) is rotated around the origin by an angle θ, the new coordinates (x′, y′) are x′ = x cos⁡(θ) − y sin⁡(θ).

  1. Reflection:

When you flip the rectangle over a specified axis (x-axis, y-axis, or another line), the orientation of the rectangle changes to its mirror image. Reflection over the x-axis (x, y) becomes (x, −y).Reflection over the y-axis (x, y)becomes (−x, y) and over the line y=x,(x,y) becomes (y, x).

  1. Dilation:

When you resizing the rectangle by expanding or contracting it at the origin point, usually the shape of the rectangle remains the same, but its size changes.

If the rectangle is dilated by a scale factor k, the new coordinates (x′,y′) are x′ = kx, y′ = ky. However, each transformation changes the position, orientation, or size of the rectangle on the coordinate grid. By applying these transformations, you can manipulate the rectangle for different mathematical analyses.
