Multivariable Calculus
Introduction In engineering, we come across various systems where the process depends on more than one variable. In this case, the optimization and designing of the system need the involvement of multiple variables. In this direction, multivariable calculus plays an important role. It has various applications starting from economics to science. In this tutorial, we will learn about multivariable calculus and its various operations (such as limits, continuity, partial derivatives, and integration) with solved examples. What is meant by Multivariable Calculus Multivariable calculus is an extended topic of calculus that includes multiple variable functions. ...
Read MoreNature of Roots of Quadratic Equation
Introduction The solutions of the quadratic equation ax2+bx+c=0 serve as the quadratic equation's roots. They are the values of the variable x that the equation requires. The x-coordinates of the x-intercepts of a quadratic function are the roots of the function. A quadratic equation can only have a maximum of two roots because its degree is 2. The nature of these roots of the quadratic equation is solely dependent on the value of the determining factor which is called a discriminant of the quadratic equation about which we will be discussing in this tutorial. Quadratic Equation ...
Read MorePlace Value Worksheets
Introduction Place value is the foundation for understanding number systems in mathematics. Place value helps in understanding the base 10 number system. Place value worksheet is an important tool to understand the concept, and helps students develop logical, problem-solving and reasoning skills. Place Value Each digit in a multi-digit number has a specific position in that number, which is defined by the base 10 number system. When a multi-digit number is written in numerical form, the position of a number can vary from unit to infinity. Place Value Chart For a 10-digit number, the following table represents the placement of ...
Read MoreMaxima & Minima Using First Derivative Test
Introduction Usually, various physical entities are expressed in a mathematical equation that includes several variables. A function can represent the nature of variables during the process. A function can be graphically presented between the variable and the desired response. However, most of the time, we need to find the specific points at which the function gives a maximum and a minimum value. In this direction, the derivative test, which is a fundamental concept of calculus, is found to be quite helpful. In this tutorial, we will learn about the derivative, its application in optimization, and the determination of maxima and ...
Read MoreMultiple Regression
Introduction Before we learn about multiple linear regression, let us understand what linear regression is. Linear regression helps in determining the relationship between two variables in data sets. As already stated linear regression has its limitation to two variables. Therefore, multiple linear regression helps in determining the relationship between more than two variables. Though multiple linear regression cannot overcome the weakness of linear regression, multiple linear regression is used to make a regression model with multiple independent variables and single dependent variable. Multiple linear regression is used most importantly in econometrics and financial inference. Definition Simple ...
Read MoreMultiplication Rule of Probability
Introduction Probability is the possibility of happening an event. In the other words, it is the ratio of the total number of favorable outcomes to the total number of favorable outcomes and if the probability is one it means an event is a sure event or if the probability is zero then it means that event will not happen. Probability is simply a useful description (in the form of a mathematical model) for experiments whose exact outcome is difficult to predict in advance When you toss a coin, it's tough to know in advance if a head or a ...

Read MoreRecycler view item animate when scrolling in Android
Before getting into Item animation for recycler view example, we should know what is Recycler view in android. Recycler view is a more advanced version of the list view and it works based on View holder design pattern. Using recycler view we can show grids and list of items. card view is extended by frame layout and it is used to show items in card manner. It supports radius and shadow as predefined tags. This example demonstrates how to integrate Animation in Recycler View with card view by creating a beautiful student records app that displays student name with age. ...
Read MoreOverview of Arduino IoT boards
Arduino has come up with a number of boards specifically for Internet of Things (IoT) applications. If you go to the Products page on Arduino website, you will find a separate section for IoT boards. Their prices range from $18 to $69.The main feature that differentiates these boards from other Arduino boards (like Uno) is the presence of some connectivity onboard. For instance, The Arduino Nano 33 IOT board has WiFi and Bluetooth connectivity.The MKR Fox 1200 board (available in Europe only) supports the Sigfox architecture.The MKR GSM 1400 board supports GSM.The MKR NB 1500 supports the recently developed NBIoT ...
Read MoreIntegrating .NET application with SAP system and using best practices
To connect a .NET application with SAP system, there are different approaches that you can follow:Use of SAP PI middleware that offers different protocols and communication framework for integration of two systems. SAP PI/XI enables you to set up cross system communication and integration and allows you to connect SAP and non-SAP systems based on different programming language like Java and SAP ABAP. It provides an open source environment that is necessary in complex system landscape for the integration of systems and for communication.SAP Process Integration is a middleware to allow seamless integration between SAP and non-SAP application in a ...
