2 Essential functions for learning all in one
A wide range of essential functions are effective for education and available to support student’s learning.
-
-
Spreadsheet
Useful for learning statistics.
Up to 5 columns x 45 rows
(maximum of 170 data items)
1Essential functions
Even advanced mathematical calculations are simple to perform and functions that take advantage of previous unavailable display capabilities are now possible.
Spreadsheet calculations
Statistics
The spreadsheet function can be used for studying statistics which has become important in mathematics classes.
Example: Student’s height data comparison chart
Statistical calculation such as the mean of the data is executed
Recursion
In addition, the spreadsheet function makes it possible to enter recursive formulas.
Sequence: a1=2 and an+1 -2an-3 (n=1, 2, 3 …)
a1-2, a2=1, a3=-1, a4=-5, a5=-13
Riemann Integral
Calculation using advanced Riemann functions is also possible.
The spreadsheet function makes it easy to use real-world data even in the classroom, enabling students to effectively study statistical processing.
2Variety of functions available to support student’s learning.
From basic level to advanced math level for secondary and tertiary education.
