Using scientific calculator with shift for engineering

When using the scientific calculator with shift for engineering purposes, you can interact with the numbers and functions just like you would with a standard calculator. Simply click on the buttons corresponding to the numbers and functions you need.

In scientific mode, additional functions are available such as exponentiation (y^x), square root (√x), scientific notation (EE), and opening round brackets. When you click on the add (+), subtract (-), multiply (×), divide (÷), or any of the scientific functions, a white ring will appear around the button you clicked. This ring serves as a visual indicator to confirm the operation that will be carried out.

Furthermore, when you click on the opened round bracket, the ring around it will remain visible until all parentheses expressions are closed. This feature helps you keep track of the parentheses and ensures that you correctly complete all calculations within the brackets.

By providing these visual cues, the calculator helps you maintain accuracy and prevents errors when performing engineering calculations. You can confidently use the calculator's functions and rely on the visual indicators to ensure precise and efficient calculations.

Who invented the pocket calculator?

The invention of the pocket calculator can be attributed to several individuals and companies who made significant contributions to its development. However, one notable figure in the creation of the first handheld calculator is Jack Kilby, who led the research project at Texas Instruments.

In 1967, Kilby and his team at Texas Instruments developed a prototype called "Cal Tech," which served as an early version of the handheld calculator. The Cal Tech calculator was capable of performing basic arithmetic operations such as addition, multiplication, subtraction, and division. Its output device utilized a paper tape to display the results.

The development of the Cal Tech calculator marked a significant advancement in calculator technology. It showcased the potential of using integrated circuits (chips) with low power consumption, which enabled the creation of portable calculators that could operate on rechargeable batteries.

Although the Cal Tech calculator was a prototype, it laid the foundation for subsequent advancements in pocket calculator design and paved the way for the commercial production of handheld calculators. In the years following the Cal Tech prototype, numerous companies and inventors further refined and commercialized pocket calculators, leading to the widespread availability and use of these portable computing devices.

It is important to note that the invention of the pocket calculator was a collective effort involving contributions from various individuals and companies. Jack Kilby's work on the Cal Tech prototype played a significant role in the early stages of calculator development and set the stage for the future evolution of handheld calculators.

Who invented the programmable pocket calculator?

The programmable pocket calculator, known as the HP-65, was invented by a team at Hewlett-Packard (HP) in 1974. This calculator was a groundbreaking innovation as it allowed users to store and retrieve programs using a built-in magnetic card reader.

The HP-65 was the first handheld calculator that offered programmability, enabling users to create and execute customized sequences of instructions. It had a capacity to store up to 100 instructions or steps in its memory, providing users with the ability to perform complex calculations and automate repetitive tasks.

The inclusion of a magnetic card reader in the HP-65 was a significant advancement. It allowed users to save their programs onto magnetic cards, which could be easily inserted into the calculator for program execution or retrieval. This feature facilitated the sharing and transfer of programs between different HP-65 calculators.

The development of the HP-65 was a collaborative effort by the engineering team at Hewlett-Packard, including individuals such as William Hewlett, David Cochran, and others. Their work on the HP-65 set the stage for subsequent advancements in programmable pocket calculators and revolutionized the way calculations were performed in various fields such as engineering, science, and finance.

The HP-65 not only introduced programmability but also demonstrated the potential for handheld calculators to be versatile computing devices that could be customized to meet specific needs. It paved the way for future generations of programmable calculators and contributed to the evolution of portable computing technology.

Which is the latest scientific calculator?

As of my knowledge cutoff in September 2021, the latest scientific calculator from Casio is the fx-991EX Classwiz. It offers enhanced features compared to its predecessor, the fx-991ES Plus. The fx-991EX Classwiz is known for its improved speed, boasting four times faster processing capabilities. Additionally, it provides a higher resolution display, making it easier for users to view and interpret calculations.

The Classwiz series, including the fx-991EX, is designed with an intuitive user interface, making it user-friendly and suitable for educational purposes. It incorporates high-performance functions and a range of mathematical capabilities, catering to the needs of students, teachers, and professionals alike.

Please note that advancements in calculator technology continue to be made, and there may be newer scientific calculator models available beyond my knowledge cutoff. I would recommend referring to official sources or contacting Casio directly for the most up-to-date information on their latest scientific calculator offerings.

Is fx 991 ex allowed in ESE exams?

The Casio fx-991EX Classwiz is generally allowed in engineering services exams (ESE) conducted by the Union Public Service Commission (UPSC). According to UPSC guidelines, non-programmable calculators are typically permitted for use during the examination.

The fx-991EX Classwiz is a non-programmable scientific calculator, which means it is designed specifically for mathematical calculations and does not have programmable functions or capabilities. It is commonly accepted for use in various educational and professional settings, including engineering exams.

However, it's important to note that specific rules and regulations regarding calculator usage may vary depending on the examination and the examination authority. It is always recommended to check the latest guidelines and instructions provided by the exam conducting body or consult the official exam notification to ensure compliance with the permitted calculator models.

If you are planning to appear for the ESE or any other specific examination, I would advise you to refer to the official guidelines provided by the exam conducting authority or reach out to the relevant authorities for the most accurate and up-to-date information regarding the permissible calculator models.

How do I know if my Casio scientific calculator is real?

To verify the authenticity of your Casio scientific calculator, you can follow these steps:

  1. Display the QR code on the calculator: Turn on your Casio calculator by pressing the "ON" button. Then, press the "MODE" button followed by "0" to display the QR code on the calculator's screen.

  2. Read the QR code with a smartphone or tablet: Use your smartphone or tablet to scan the QR code displayed on the calculator's screen. You can use a QR code scanning app or the built-in QR code scanner on your device's camera.

  3. Authenticity check and manual display: After scanning the QR code, the app or browser will display the authenticity check and the manual for your specific calculator model, such as the ESPLUS. You will see information confirming whether the calculator is authentic or not.

  4. Check the calculator's authenticity: On the app or webpage, there should be a button labeled "CHECK" or a similar option. Click on this button to perform the authenticity check of your calculator. The system will verify the authenticity based on the information provided.

  5. Register your product information (optional): If desired, you can click on the "Worldwide Education Website" or a similar link provided to register your product information on Casio's education website. This step is optional but can help you keep track of your product and access additional resources or support.
