Complex Numbers
Introduction Complex numbers make it simpler to find the square root of negative values. The concept of complex numbers was first presented when Hero of Alexandria, a Greek mathematician, attempted to compute the square root of a negative number in the first century. However, he made the integers' negative values positive and got their root values. Additionally, the identity of complex numbers was established when the third- and second-order polynomials' negative roots were discovered by the Italian mathematician Gerolamo Cardano in the sixteenth century. Numerous scientific research, including those involving signal processing, electromagnetism, fluid physics, quantum mechanics, and vibration ...
Read MoreConditional Statement
Introduction Mathematical reasoning, a crucial skill that enables pupils to examine a given hypothesis without reference to a specific context or meaning, includes conditional statements. The reasoning is not based on an individual's opinion when a scientific investigation or assertion is investigated, to put it simply. The basis for deductions and proofs must be factual and scientific. To answer issues involving mathematical reasoning, one needs to possess critical thinking and logical reasoning abilities in mathematics. We will delve into the world of conditional statements in this quick session. Along with solved examples and interactive questions, we will go over ...
Read MoreConic Sections
Introduction When a solid surface like a cone is cut by a plane it forms different sections called conic sections. There are different conic sections like a circle, ellipse, parabola, and hyperbola based on the angle at which the plane intersects with the cone axis. Circle and ellipse are closed sections whereas parabola and hyperbola are not closed the curves of these figures extend till infinity. Definition of Section of Cone When a two-dimensional plane intersects a three-dimensional right circular cone the crop section formed on the plane is called a conic section. The plane intersects the ...
Read MoreConstructions : Triangle
Introduction A triangle has three sides, and three angles these two are the important parameters in constructing a triangle. It is done using a few geometrical equipment like a protractor (to measure an angle), compass (to draw the arc for a given measured side), and ruler (to measure the side length). There are different types of triangles, and they can be constructed differently by knowing a few given sets of parameters. In this tutorial let’s see three of the cases. Construction of Triangles In general, the construction of triangles is easy when the following properties like SSS, SAS, ...
Read MoreCoordinate Geometry- class 9
Introduction The study of geometric figures using coordinate axes is known as coordinate geometry. Figures like circles, ellipses, polygons, and straight lines can be drawn and scaled on the coordinate axes with ease. Additionally, coordinate geometry facilitates algebraic operations and the study of the properties of geometric figures. Every location on this globe has coordinates that make it simple for us to find them on a map. Our planet's coordinate system is made up of fictitious lines known as latitudes and longitudes. We have the coordinate axes with the horizontal x-axis and the vertical y- axis, which are similar ...
Read MoreAPK: Android Application Package
Introduction APK is the file format used by Android to distribute and install applications. As a consequence, an APK contains all of the components required for an app to be properly installed on your device. An APK is an archive file, which means it includes several files as well as metadata about them. You've undoubtedly heard of other forms of archive files, such as ZIP and RAR. You may have heard the word APK and wondered what it meant if you own an Android smartphone. While you may use Android without ever understanding what APK stands for, doing so will ...
Read MoreEMI : Equated Monthly Installment
Introduction Equated Monthly Installments (EMI) is a popular and convenient method of repaying a loan. It is a fixed amount of money that a borrower pays to a lender at a set date each calendar month. The EMI is designed to repay the loan, including the interest and principal, over a specific period of time. The concept of EMI is widely used for various types of loans such as home loans, car loans, personal loans, and education loans. In this article, we will discuss the concept of EMI in detail, how it is calculated, and how it can be ...
Read MoreAIDS (Acquired Immune Deficiency Syndrome)
What is AIDS? Acquired Immune Deficiency Syndrome or AIDS is an incurable and life-threatening disease caused by the Human immunodeficiency virus or HIV. This virus impacts our body immunity to a greater extent like unable to fight back any form of diseases.The major cause behind this is there is no specific line of treatment for HIV-AIDS.But with effective treatment strategies the disease can be controlled and the diseased can remain healthy for a span of time. Symptoms There are quite a lot of symptoms for AIDS but still it varies from individual to individual.Following are the different forms of ...
Read MoreHDMI: High Definition Multimedia Interface
Introduction The High Definition Multimedia Interface is one of the most popular audio/video interfaces for transferring digital audio and video from sources that support HDMI. Display controllers, compatible computer monitors, videoprojectors, digital televisions, and digital audio equipment are some examples of these gadgets. The analog video standards have been replaced by the digital standard of HDMI. Televisions, computer monitors, home entertainment systems, video displays, and many more audio-visual devices all use the HDMI interface. Due to the performance of the HDMI interface, the system is suitable for the very high data rates that must now be exchanged between components in home ...
Read MoreSIM: Subscriber Identity Module
Introduction Nowadays Nowadays, SIM cards are a vital part of our day to day activities. It allows 7 billion devices to be connected to mobile networks around the world. “As per International Card Manufacturer Association (ICMA), there were 5.4 billion SIM cards manufactured every year which leads to USD 6.5 Billion revenue for card manufacturers globally”. The increase in demand for IoT and upcoming 5G technology is expected to boost the demand for SIM. The introduction of embedded SIM (eSIM) and remote SIM provisioning (RSP) from the GSMA may disrupt the traditional SIM ecosystem and value added services of ...
