Features
A function that displays graphs and data in multiple colors. Makes it easier to distinguish between different graphs and datasets, improving clarity when analyzing complex information. Useful for students learning to visualize mathematical concepts and for analyzing data in science classes.
This model does not have a color display function. Graphs and data are displayed in monochrome, which may limit clarity for some users when analyzing complex information. The absence of color can make it harder to distinguish between multiple plots or datasets.
A function that provides a clear and detailed display of graphs and equations. Allows for more precise visualization of curves and data points, reducing ambiguity. Particularly helpful when dealing with intricate mathematical models or large datasets.
This model does not feature a high-resolution screen. The lower resolution may result in less detailed visuals of graphs and equations, potentially affecting the precision of analysis and making it harder to read intricate mathematical models.
A function that uses a rechargeable battery instead of disposable batteries. Reduces the cost of replacing batteries and is more environmentally friendly. Useful for students who use their calculators frequently and for extended periods of time.
This model does not come with a rechargeable battery function. It relies on disposable AAA batteries, which may require frequent replacements for heavy users. This can increase the long-term cost and environmental impact of using the calculator.
A function that allows the creation and visualization of three-dimensional graphs. Enhances the understanding of spatial relationships in mathematical and scientific models. Beneficial for students taking advanced math courses or those studying subjects like physics and engineering.
This model does not support 3D graphing. Users are limited to 2D plots, which may hinder the visualization and understanding of three-dimensional mathematical relationships. This can be a significant limitation for advanced math and science courses.
A function that allows connection to a computer via USB. Enables the transfer of data, programs, and screen captures between the calculator and a computer. Useful for creating reports, sharing data, and updating the calculator's software.
This model does not offer computer connectivity via USB or other means. This limits the ability to transfer data, update software, or create reports, making it more difficult to integrate with modern learning environments and workflows.
A function that performs symbolic calculations, such as simplifying expressions and solving equations algebraically. Simplifies complex mathematical operations, allowing students to focus on understanding the concepts rather than manual computation. Particularly useful for advanced mathematics courses.
This model does not include a Computer Algebra System (CAS). Users cannot perform symbolic calculations or algebraic manipulations, which can be a significant limitation for advanced mathematics courses where understanding concepts is prioritized over manual computation.
