Casio is a publicly traded company, so it is owned by its shareholders. The largest shareholders typically include institutional investors and individual shareholders. The company was founded by Tadao Kashio in 1946, and while the Kashio family remains influential in its management, it does not have a single owner.

To determine the rate of change using a graphing calculator, first input the function you want to analyze into the calculator. Then, use the "calculate" feature to find the derivative at a specific point, which represents the rate of change at that point. Alternatively, you can graph the function and use the "slope" or "tangent line" features to visually assess the rate of change over an interval. The numerical value of the derivative or slope will give you the rate of change.

The Casio fx-50FH scientific calculator was introduced in 1985. It was part of Casio's line of calculators that combined advanced mathematical functions with a user-friendly interface, catering to students and professionals alike.

A simple calculator typically has around 10 to 15 buttons, which include the numbers 0 through 9, basic operations (addition, subtraction, multiplication, division), a clear or reset button, and sometimes additional functions like square root or percentage. The exact number can vary depending on the specific model and its features.

DMS on a calculator stands for Degrees, Minutes, and Seconds, which is a way to express angles in a sexagesimal system. In this format, an angle is represented as degrees (°), minutes ('), and seconds ("). For example, 45° 30' 15" indicates 45 degrees, 30 minutes, and 15 seconds. Many scientific and graphing calculators have a DMS mode to facilitate conversions between decimal degrees and DMS format.

A graphing calculator allows you to visually compare two trigonometric expressions by plotting them on the same coordinate plane. If the graphs overlap completely, it indicates that the expressions are equivalent for all values of the variable. Additionally, the calculator can evaluate specific points to confirm equivalence at those points. This visual and numerical approach makes it easier to understand the relationships between the expressions.

The New York State Education Department allows the use of specific graphing calculators during the Regents exams, particularly the TI-83 and TI-84 series from Texas Instruments, as well as certain models from Casio and HP.
