CASIO Advanced Scientific Computer fx-991CW is the highest specification standard scientific/engineering computer (not programmable) available91EX is a new generation of evolution. Although the product model continues to use the familiar 991 in the past, the user interface of the computer is optimized and improved, and a lot of changes have been made to the screen, button appearance and sorting design.

ClassWiz's CW series is designed for secondary school teachers and students around the world, and it is time to define the new value of computing in the face of the new era of computing in the future.

The fx-991CW is easy for beginners to learn and more satisfied for old customers. It is suitable for "prospective college students" who are going to the first year of high school in Taiwan, and is more suitable for college students studying various departments, whether your major is electrical engineering and engineering, business management and social science, or you are studying graduate school, or you are a professional. Whether it comes to studying, exams, measurement calculations, professional business or engineering applications , the fx-991CW's innovative design and powerful features allow you to cope with any situation.

Applicable Audience/Scope

+High school teacher

Individual teaching research/special courses

+Freshman Compulsory basic course

Calculus, Introduction to Computing, General Physics, General Chemistry, General Physics/Chemistry Laboratory Courses

+University Electrical Engineering Core Course

Engineering Mathematics, Electronics, Circuits, Electromagnetism, Applied Mechanics, Thermodynamics, Materials Mechanics, Dynamics, Fluid Mechanics, Mathematical Statistics, Numerical Analysis....

+The core course of business management and social sciences of the university

Individual/Global Economics, Statistics, Regression Analysis, Economic Mathematics, Management Mathematics, Investing, Financial Management....

※The courses listed above only indicate that computer functions can be used for the computing needs of each course. /b13> Whether it can be used in the test is still subject to the norms of the professors or teaching assistants of each university .

Is there a tool that can be used for teaching, assessing exams, or for engineers or business people? /b10>The fx-991CW was created for these needs.

The following is a brief introduction to the appearance and function changes of the fx-991CW, and more information can be found in each topic chapter.

In addition to black and white in the world, there are also gray areas, fx-991CW LCD liquid crystal has black, dark gray, light gray and white 4-gradation display (4-gradation display), The new specs make the computer different.

The resolution of the CW series inherits the EX, and the screen resolution is 192×63 in dot matrix, which is about 4 times that of the ES series, and can display more details.

Even a standard scientific computer should bring users a good visual experience. High resolution and color level performance can bring more subtle differences to mathematical input, and the performance of graphical display is richer.

B Perform calculations faster and more precisely

Most of the computational problems that need to be solved by science and business management departments in high schools and universities, although most scientific computers can do it today, sometimes the calculation of complex problems still takes some time.

For example, if the number of stages is calculated ∑ =11000(1) fx-991CW only needs 25/b111>seconds, 1 times faster than EX.

Faster calculation speed, whether in the exam, or when measuring and calculating can save you valuable time. In addition, compared with the 15-digit internal computing number of scientific computers in the past, the fx-991CW can reach 23 digits, which is more reliable.

When people interact with technology products, they need to be creatively designed. Some computer keys are not necessarily even computer keyboards!

CW series opens up circular key thinking, breaks the boundaries of traditional computer square keys, allows users to easily use force from different directions, and makes computer key sorting more beautiful.

The direction/cursor keys become !$+|ng. /b14>The Menu key became the HOME button w design, combined with the idea of a modern handheld 3C device. Simplified and rearranged buttons, created to improve the user experience.

For more information, please refer to the first half of the "Design Improvement Article" for detailed instructions on button design. 

Q function improvement + new product design

In addition to the buttons, the fx-991CW computer also has a better appearance, with a black matte body body, with a hard border around it, and a diamond check thought from CASIO product engineers. The overall design adopts black, gray, white and gold colors, which is more elegant than ES and EX series.

The 991 series is an evergreen masterpiece of CASIO's scientific computer, from computing mode to statistics, distribution function, and then to various modes. The original function has been very perfect, which can be applied to most of the needs of students in Taiwan's higher education, such as electrical resources, science and engineering, business management and social sciences, but CASIO expects to improve it.

New computer functions or improvements to existing functions can bring faster and better results to teaching exams or engineering calculations. For example, the variable keys of the fx-991CW can be /modified directly in the menu, and the new function of its dual functions can be combined differently. More information can be found in the second half of the "Design Improvement Article" and the "Function Detailed Chapter".
