# Features

## 1 Easy and Intuitive operability

Intuitive feature makes it easy to use the features of fx-CP400.

This feature makes the fx-CP400 ideal for mathematics learning.

*1*Touch panel

The fx-CP400 offers intuitive operation through use of the stylus on the touch panel.

*2*Pinch-in and Pinch-out

Intuitive pinch-in / pinch-out control allows you to easily adjust a graph to the exact display size that you desire as zoom in or zoom out.

*3*Slider function

By slider function to the Graph / Geometry the control to freely change values allows you to learn their relationship with other values by freely changing shapes

*4*Drag and drop

Mathematical formulas can be graphically displayed without any complicated key operations - simply drag and drop the formula into the graph area!

## 2 Essential functions for learning all in one

CAS Graphing calculators have a variety of functions covering from primary to higher education. Students can cultivate mathematical thinking through Graph functions operated by themselves.

*1*Calculation using CAS

CAS(Computer Algebra System) is a software program facilitating symbolic mathematics.

Expand, Factor, Simplify calculations

Solve, Complex, Vector calculations

Limit, Differentiation, Integration calculations

Differential equation, Taylor polynomial, Laplace transform calculations

Upright? Horizontal? Both!

### Interactive Differential Calculus

Visual, intuitive operations make it possible to learn the concept of differentials which is often hard to understand for students.

Function and tangents

Plot coordinates of the slope of a tangent and predict the function

Function and its first derivative formula

You can learn differential coefficients and derivative formulas by exploring this function.

### Differential Equation Graph

The solution set of differential equations can be represented as graphs in vector fields, and solution curves can be drawn by providing initial conditions of the equations.

## Comment

The invention of the graphing calculator forever changed the face of mathematics education. I feel that the Casio fx-CP400 has once again changed how we teach mathematics. The ability to interact with equations and graphs on a single screen is revolutionary. I can now focus on the connections between concepts. The fx-CP400 allows me to explore connections between geometry, statistics and data analysis through the use of data collections. It allows my students to make conjectures and model the mathematics that is right in front of them. The ability to graph in 3D allows my students to see the world in a whole new way and allows them to ask and answer questions I have never been able to ask them before.
