Casio FX9750GII Graphing Calculators and its Uses

## Introduction

A calculator is a tool used in mathematics that facilitates calculating. Calculators can only perform addition, subtraction, multiplication, and division in their most basic configuration. A graphing calculator is a particular kind of calculator that can create and present mathematical graphs. Additionally, a calculator of this kind is capable of handling simultaneous and pictorial equations. These calculators can also carry out variable-based mathematical operations. Since most graphing calculators can be programmed, they are similar to computers. This gives users the ability to create unique mathematical programmes for their particular tasks. The calculators may simultaneously display calculations, graphs, and texts on their displays.

A graphing calculator made by Casio America Inc. is the Casio FX9750GII (also known as Casio’s 9750). (Casio worldwide education, 2009). The 9750 calculators from Casio first hit the market in 2009. Users can upload mathematical programmes and update the operating systems of their calculators with this calculator, which is easy to use. The USB part of the Casio FX9750GII graphing calculator enables it to upgrade its operating systems. In comparison to other graphing calculators, the calculator is inexpensive and easy to use. This essay’s goal is to explain how to use and operate the Casio FX9750GII graphing calculator.

## Brief Explanation on how to use Casio FX9750GII Graphing Calculator

Before you tackle any math problem, it’s crucial to make sure the following in order to utilise the Casio FX9750GII graphing calculator (Casio worldwide education, 2009). First, make sure that the calculator’s mode is appropriate for the problem you are working on. Use the mode button to configure your calculator in the appropriate mode for the current problem. This button enables the user to alter settings like degrees f and radians r(i) (x). For instance, you must switch the calculator’s mode to degree mode if the arithmetic issue you are addressing requires working in degrees. You must do this before attempting to solve the issue. The same holds true for other types of modes.

Also, make sure you have the numbers for y before attempting to create a graph with the Casio FX9750GII Graphing Calculator. As a result, you can use this calculator to plot data, but first you need y values. Only equations with y values are accepted by the calculators by default. This is a crucial element since it makes it possible to plot the graph.

Therefore, be familiar with the calculator’s shortcut menus and how to use its features. Find the calculators’ mathematical shortcuts by looking behind the graphing calculator. For instance, make sure you understand how to enter matrices, convert fractions to decimals, and locate square roots of integers. These shortened methods are beneficial for performing calculations (Casio worldwide education, 2009). Make sure you understand the mathematical symbols on the calculator’s button.

## How to Calculate Domain and Range using Casio FX9750GII Graphing Calculator

The bounds and restrictions of a function are displayed via the domain and range. The domain of a function is the collection of x values in an equation or a graphic. The range of functions is represented by the y-values returned by a function or equation. Varied function types produce different results in terms of domain and range. By looking at the graph table, you may find the domain and range of the function.

Key symbols Function: The keys on the calculator have multiple uses. Each keyboard key and button has a color-coded function. This makes it quick and simple to pinpoint the task you want to perform.

For instance, figure out log 90. Just write press log keyboard followed by 90 to get the solution. The result is 1.95 after pressing the equal sign button.

You then press the shift (2nd lock) and log buttons to locate the 10x. This assists you in locating the solution you need.

Alpha lock: To type the letters a, b, c, or d on a calculator, hit alpha lock first, then the button for the desired letter.

### Mathematical manual

From left to right, enter the mathematical computations exactly as written. To place a minus sign before a negative value, use the key () input. Internal calculations are made using 15 digits, and the output is displayed as a round 10-digit mantissa. Division, multiplication, addition, and finally subtraction are the input steps for a mixed calculation.

For instance, the expression (2*10)+5–6 should be put from left to right as printed.

Even if you choose a certain number of decimal places, internal calculations still use a 15-digit mantissa and a 10-digit mantissa for the answer values shown on the screen.

The number of significant digits (Sci) and decimal places (Fix) that have been specified remains fixed until the normal display range (Norm) keyboard is used to adjust the setting.

For instance, 100/6 equals 16.6666666.

## Conclusion

A graphing calculator made by Casio America Inc. is the Casio FX9750GII (also known as Casio’s 9750). In 2009, Casio’s 9750 calculators were released on the market. This calculator is easy to use and lets users upload mathematical applications in addition to updating calculator operating systems. Additionally, a calculator of this kind is capable of handling simultaneous and pictorial equations. These kind of calculators can also do variable-based mathematical computations. Since most graphing calculators can be programmed, they are similar to computers. This gives users the ability to create unique mathematical programmes for their particular tasks. The Casio FX9750GII is very easy to use and performs well. Although it lacks some of the capabilities and applications included in today’s latest graphing calculators,

So, make sure you have the numbers for y before attempting to create a graph with the Casio FX9750GII Graphing Calculator. As a result, you can use this calculator to plot data, but first you need y values. Only equations with y values are accepted by the calculators by default. This is a crucial element since it makes it possible to plot the graph. Consequently, be familiar with the calculator’s shortcut menus and how to use its features. Find the calculators’ mathematical shortcuts by looking behind the graphing calculator. For instance, make sure you understand how to enter matrices, convert fractions to decimals, and locate square roots of integers.
