Introduction A chord is a line segment connecting any two points located on the circumference of the circle . The circle is a well-known two-dimensional shape used in Euclidean geometry. It has various components, including chord, radius, diameter, etc. In this tutorial, we will discuss the definition, formulae, and some theorems related to the chord of a circle. Circles The circle is a two-dimensional figure drawn on a plane in such a way that each point on the circle is equidistant to a fixed point. The fixed point is known as the center of the circle. The dimension of ... Read More
Introduction Completing the square is an algebraic technique for writing a quadratic expression that contains the perfect square . The Quadratic Formula is the most basic method for determining the roots of a quadratic equation. Certain quadratic equations cannot be easily factorised, and in these cases, we can use this quadratic formula to find the roots as quickly as possible. The roots of the quadratic equation also aid in determining the sum and product of the roots of the quadratic equation. The quadratic formula's two roots are presented as a single expression. The positive and negative signs can be used ... Read More
Introduction A cone has a curved surface at the bottom; therefore, it contains two surface areas that are total surface area is the total surface area covered by the cone, whereas the curved surface the area consists of the surface area covered by the curved surface, which is the surface area other than the bottom circular flat surface. A cone has a vertex or an apex and a slant height. In this tutorial, we will discuss cones, slant height, curved surface area, total surface area, and a few solved examples. Cones Cones are three-dimensional figures with a circular surface at ... Read More
Introduction A cuboid is a solid shape or a three-dimensional shape in geometry. A cuboid is an 8 vertices, 12 edges, and 6 rectangular faces convex polyhedron. A cuboid is also known as a rectangular prism. An example of a cuboid in the real world is a rectangular box. What is cuboid? Imagine a shape that results from stacking numerous congruent rectangles on top of one another. The resultant shape is known as a cuboid. Dimensions of a Cuboid In order to describe the length, width (breadth), or height of an edge of a cuboid shape, it should be ... Read More
Introduction A diagonal matrix is a matrix in which the entries outside the main diagonal are all zero. Matrices are used in practical life events like military parades, school parades, and planting. The concept of matrix and determinant is recorded as having appeared in the fourth century B.C, although its use is thought to have begun only in the second century BC. Then, towards the end of the seventeenth century, the concept of matrix and determinants came back into use. Mathematical models of everyday world problems are formed as sets of linear equations. Matrices are essential and inevitable to solve ... Read More
Introduction Area of a quadrilateral is the region enclosed by the sides of the quadrilateral. The quantity of territory contained within a quadrilateral determines its area. Let's review the definition of a quadrilateral. A closed shape with four line segments enclosing it is referred to as a quadrilateral. Both regular and irregular quadrilaterals exist. A quadrilateral with regular sides is one with equal-length sides. An irregular quadrilateral is a quadrilateral that is not regular. There are six different kinds of quadrilaterals. Square, rectangle, parallelogram, trapezoid, rhombus, kite, etc. In this tutorial, we discuss areas of all these quadrilaterals. We'll ... Read More
Introduction Area of trapezium is the region covered by a trapezium in a two-dimensional plane. A trapezoid is a convex quadrilateral with exactly one pair of parallel sides. A trapezoid is a two-dimensional shape. It looks like a table if we draw it on paper. A quadrilateral can be described as a polygon that has exactly four sides and four vertices in the terms of Euclidian geometry. The number of sides, corners of a trapezium is always four and it is always constant. There are many examples of trapezoids in the real world. The fundamental use of trapezoids is the ... Read More
Introduction Area is the space occupied by a figure. Polygons are the two-dimensional shape which has plane closed figures made of the line segments. Based on the number of sides each name of the polygon varies such as, triangles, quadrilateral, etc. The circle and ellipse are closed two dimensional shapes that have no sides. Area is a two-dimensional measurement that represents the amount of space covered by a two-dimensional shape. Area Area is the space inside a 2D shape. To measure the area of polygons, when the figure is in the grid, we can use unit squares. By ... Read More
Introduction Arithmetic Geometric progression is a sequence of numbers in which each element is arranged in such an order that ratio of two consecutive terms always remains the same. In mathematics, a sequence is a collection of numbers arranged in an order that each element in the sequence corresponds to the position and value of the next element. Sequence is the basis for calculating infinite series in advanced mathematics. In this tutorial, we will study arithmetic progression, nth term formula, sum of n terms of an arithmetic progression and some solved examples. Sequence A collection of numbers which can be ...

Before getting into the ways of creating a file using Bash, let's first understand how Linux treats its files. Linux organizes all its data into files and files are organized into directories. Further, the directories are organized into tree-like structures called the file system. When you have to work in a Linux environment, you would definitely have to spend a lot of your time working on different types of files.There are various ways in which one can create a file in Linux. You can create a file from the Bash Shell or you can use the Desktop File Manager to ... Read More
