Graphing is an important data tabulation process that maths students learn. The process requires graph paper. It is a paper that is divided into a matrix of 1cm cells. Initially, the students use regular graph paper. Later on, when they need to present values in terms of degrees, radians, or angles, they employ polar graph papers. A polar graph paper is a circular graph paper used to project polar coordinates. Creating one by yourself can be a time-consuming process. So, why indulge in it when you can use free printable polar graph paper templates?
To make it even easier for you, we’ve made some graphs for you to download for free. Pdf format is also available. Before you click that button, let’s talk a little about where exactly you can use these polar graphs.
Real-life applications of polar graphs
Polar graphs are a mathematician’s trusted tool for finding coordinates of a point in a 2-D space. These are used for defining the location of an object while navigating.
Facts like the sensitivity of sound captured by a microphone can also be ascertained with the use of polar graphs.
Polar graph, that is circular in shape resembles the recording pattern of sound. By using the equation, r = sin (theta), one can find the way the sound is picked by the microphone.
A number of devices used in real life, such as shotgun, microphone, GPS, and even a cellphone employ polar graphs and their coordinates for finding some functionality-related variables.
Free polar chart templates types included in our bundle
Polar charts included in our bundle are designed in four styles. The polar chart equations are based on angles, radians, and accordingly, we have designed styles depending upon the kind of calculation one needs to find.
- Blank polar graph paper: It is a truly customizable style that users can employ to find the coordinates as intended.
- Polar graph paper with angles: A polar graph resembles a circle. Since the circle can be divided into sectors at angles ranging from 0 to 360 degrees, it is a good fit for the angles-based calculations.
- Radians-based polar graph: Angles can also be represented as radians. If you need to simplify graphing activity that involves radians, you can employ this style.
- Polar graph template with more lines: You may need to locate the coordinates at finer angles. In such cases, you can employ the polar graph paper with more demarcations as displayed in our fourth style.
Do you know?
Polar graph papers merge Euclidean Geometry with the principles of Algebra. This system of graphing is useful in coordinate geometry. It was invented by René Descartes in the 17th century.
In a polar command, the (x,y) coordinates are replaced by (r,θ) where θ is the counterclockwise angle made with respect to the x-axis. Also, r is the position of an object from the point of origin.
Polar graph charts can be made using a ruler, compass, or protractor. But, that comes with the possibility of human error. Instead, you can download and use our printable polar chart PDF templates, and get them printed whenever needed. Our templates are verified for correctness and can serve as readymade practice material for solving equations of coordinate geometry.
